Reaction Steps
To a stirring solution of ethyl 2-nitrobenzoate (1.0 g, 5.12 mmol), sodium acetate trihydrate (4.18 g, 30.7 mmol) in solvent mixture of MeOH (7 ml) and THF (7 ml) was added stannous chloride dihydrate (3.47 g, 15.37 mmol) slowly at 10-20° C. Reaction mixture was stirred at 25-30° C. for 16 h. Reaction mixture was diluted with water and basified with aq. sodium bicarbonate solution. Product was extracted with ethyl acetate. The organic layer was separated and distilled out to get crude product which was stirred with hexane to get white solid in 80% yield.
