Abstract

The process is characterised in that p-nitrobenzoic acid is esterified in butanol in a manner known per se, the nitro ester is catalytically hydrogenated without intermediate isolation and the resulting hydrogenation solution, after removal by distillation of the majority of the alcohol used, is reacted with diethylaminoethanol in the presence of alkali metal alkoxides at 80 to 150 DEG C, preferably 80 to 130 DEG C, and in the course of this the alcohol liberated is continuously removed in vacuo.
