Methyl 4-methoxy-2-nitrobenzoate → Methyl 2-amino-4-methoxybenzoate

関与物質

反応手順

A solution of methyl 4-methoxy-2-nitrobenzoate (9.0 g, 43 mmol) in MeOH (100 mL) was degassed and purged with nitrogen. To this solution was added 10% palladium hydroxide on carbon (1.2 g). The reaction mixture was degassed, purged with hydrogen and allowed to stir at rt overnight. The reaction mixture was filtered through Celite®, the Celite was washed with MeOH and the filtrate was concentrated to give methyl 2-amino-4-methoxybenzoate (7.80 g, 76%) as a brown solid. LCMS (FA): m/z=182.1 (M+H).
