Procedure

A mixture of methyl 3,5-dimethoxy-2-nitrobenzoate (Ger 501,609, April 2, 1927; CA. 24, 47929) (39.0 g; 0.162 mole), 5% Pd on charcoal (2.0 g), methanol (200 ml) and tetrahydrofuran (200 ml) is shaken in an atmosphere of hydrogen at 52 lb pressure for 46 h when theoretical amount of hydrogen is absorbed. The catalyst is filtered off and the filtrate is evaporated to dryness. The residue is recrystallized from methanol. Yield 28.6 g; mp 93°-5°.
