These common heterocyclic compound, 191348-14-8, name is 2-Iodo-4-methoxyaniline, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route. Safety of 2-Iodo-4-methoxyaniline
Under anhydrous and anaerobic conditions, 0.1 mmol of 2-iodo-4-methoxyaniline, 0.12 mmol of 3-fluoro-4-methoxybenzaldehyde, 0.3 mmol of selenium powder, 0.005 mmol of copper, 0.2 mmol of potassium hydroxide and 10 ml were added. DMSO solution in a single-mouth round bottom flaskIn the reflux reaction at 120 C, the reaction was monitored by TLC, and the pure methoxy-containing benzoselenazole compound was obtained by column chromatography.The product was demethylated with boron tribromide (6 eq.) to give the product as a white solid.The yield was 28%.
The synthetic route of 2-Iodo-4-methoxyaniline has been constantly updated, and we look forward to future research findings.
