Procedure

10 g (39.5 mmol) of methyl 2-benzoylamino-3-dimethylaminoacrylate and 11.3 g (118 mmol) of 2-aminothiazole were dissolved at 40° C. in 200 ml of isopropanol. The solution was admixed with 3.96 ml (48 mmol) of concentrated hydrochloric acid within 5 minutes (min) and stirred for a further 60 min. 75 ml of deionized water were added, the suspension was cooled overnight and the crystallized product was filtered off.

Workup
