Procedure

A mixture of 27.0 g (91 mmol) of N-butyl-N′-(4-methoxy-2-nitrophenyl)-oxalamide, 1200 ml of methanol and 7.3 g of 10% Pd/C catalyst is hydogenated for 3 h. The catalyst is filtered off, washed with aceton, the filtrate is concentrated and the residue is treated with 100 ml of diethyl ether. The obtained product is filtered, washed with diethyl ether and dried to yield 21.8 g (90%) of the title compound. Mp.: 180-181° C. (diethyl ether).
