Procedure

A mixture of methyl 3-[methyl(methylsulfonyl)amino]-5-nitrobenzoate obtained in Reference Example 95.76 g (20 mmol), 10% Pd/C (50% wet) (1.50 g), methanol (80 mL) and ethyl acetate (80 mL) was stirred at room temperature under hydrogen atmosphere for 1.5 hours. The reaction solution was filtered on Celite and the solvent was evaporated to give 5.11 g (19.8 mmol) of the title compound (yield: 99%).

Workup

  1. filtrationThe reaction solution was filtered on Celite
