Procedure

To a solution of 3-methoxy-4-nitrobenzoic acid methyl ester (150 g) in methanol (600 mL) and THF (300 mL), 10% palladium-carbon (15 g) was added and the reaction mixture was agitated at 50° C. to 64° C. under hydrogen pressure of 0.9 MPa(s) for 6.5 hours. After allowing cool the reaction solution to room temperature, 134 g of the title compound was obtained by filtering the reaction solution on celite and condensing the obtained filtrate under reduced pressure. The physical properties was in agreement with the reported values (CAS#41608-64-4).
