Conditions

Temperature: 10 °C

Procedure

66 g (266 mmol) of methyl 2-benzoylamino-3-dimethylaminoacrylate and 50 g (295 mmol) of diphenylamine were dissolved at 40° C. in 1300 ml of isopropanol. The solution was admixed with 60 ml (725 mmol) of concentrated hydrochloric acid within 5 minutes (min) and stirred for a further 10 min. 550 ml of solvent were evaporated off under reduced pressure, the suspension was cooled to 10° C. and the crystallized product was filtered off.
