To 16.8 g. (0.1 mol) 4-methoxy-2-nitroaniline in 150 ml. anhydrous pyridine are added dropwise, while cooling with ice, 19.7 g. (0.1 mol) 4-tert.-butylbenzoic acid chloride. The reaction mixture is stirred for 1 hour at ambient temperature, poured into 1 liter of cold water and the precipitate obtained is filtered off with suction. There are obtained 32.3 g. (98% of theory) of the title compound in the form of yellow crystals; m.p. 103°-107° C.
