Formula: C7H6BrIO

To a solution of 4-bromo-1-iodo-2-methoxy-benzene (11.44 mmol, 3.581 g) in dryTHF (17.91 mL) under an atmosphere of nitrogen at -78C was added a solution ofisopropylmagnesium chloride in THF (1.3 mol/L, 11.0 mL, 14.30 mmol) over a period of 10 minutes, maintaining the reaction temperature between -65 and -70C. After stirring for 20 minutes, the reaction mixture was warmed to room temperature over one hour. The reaction mixture was cooled again to -78C and a solution of furan-2-carbaldehyde (13.73 mmol, 1.319 g) in THF (3.581 mL) was added over 5 minutes, whilst maintaining the reaction temperature between -65 and -70C. After 30 minutes, the reaction was allowed to warm to room temperature and stirred for a further 60 minutes. The reaction was quenched by the addition of saturated aqueous ammonium chloride. The aqueous layer was extracted with ethyl acetate, thecombined organic phase was dried over magnesium sulfate and the solvent removed in vacuo. The resulting residue was purified by silica gel flash chromatography (gradient elution: 0-30% ethyl acetate in hexane) to produce (4-bromo-2-methoxy- phenyl)-(2-furyl)methanol as an orange oil (1.55g, 48%). 1H NMR (400MHz, CDCI3) 7.42-7.34 (m, 1H), 7.26 (s, 1H), 7.17-7.09 (m, 1H), 7.06-6.98 (m, 1H), 6.39-6.28(m, 1H), 6.13-6.06 (m, 1H), 6.04-5.89 (m, 1H), 3.82 (s, 3H), 2.91 -2.60 (m, 1H)

Sodium nitrite (1.1 eq or 1.3 eq aniline substituent depending) was added solid or in solution (H2O/EtOH 1 M) and the reaction mixture was stirred at 0-2 C for 30 min. The solvent was removed carefully under reduced pressure without heating and can be used without further purification. 5-Amino-4-hydroxynaphtalene-2,7-disulfonic acid sodium salt (0.9 eq) was dissolved in iced water (5 mL by mmol of reagent) then pH was adjusted to 9 by adding 30% NaOH solution. The diazonium salt was added to the naphthalene moiety and pH maintained at 9 by addition of 10% NaOH solution. After complete addition of the diazonium salt to the 5-amino-4-hydroxynaphthalene-2,7-disulfonic acid monosodium salt, stirring was maintained at 0 C for 2 h. Degraded diazonium was removed after extraction with EtOAc and water soluble diazo compounds were recrystallized three times from EtOH/(H2O; pH 2) (1/1). All organic impurities were then extracted by washing with small portions of Et2O. The precipitated compounds were dried under vacuum.

General procedure: All reagents were ACS-reagent grade. Distilled water was used for the preparation of solutions. The procedure for the preparation of CaApOH is as follows: samples of 1.2g Ca(NO3)2·4H2O, 0.5g Na3PO4, and 0.04g NaOH were placed in the bottom of a 125mL Erlenmeyer flask equipped with a standard taper joint bearing a condenser with a thermometer inserted in the condenser and held slightly above the bottom of the flask (but in the solution) by a thin slice of suction tubing at the top of the condenser. The flask was placed on a heating/stir plate and 50mL of distilled water was added. The solution was stirred magnetically and heated to 80C for approximately 3h. The pH was measured, but not adjusted, at the beginning and at the end of the 3h of digestion using Hydrion pH 1.0-12.0 paper. [In order to determine the effect of pH, the pH was adjusted with 3 M NaOH for some samples at the beginning and during digestion.] Stirring was then discontinued and the solution was allowed to cool and settle overnight. The precipitate was suction filtered in a medium porosity glass filter crucible and washed 5 times with a total of about 150mL of distilled water. The precipitate was dried in a vacuum drying oven at 110 C for at least 4h and then ground with a mortar and pestle and stored in a closed, parafilmed vial.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 7681-82-5, its application will become more common.
