Conditions

Temperature: 10 °C

Procedure

10 g (39.5 mmol) of methyl 2-benzoylamino-3-dimethylaminoacrylate and 11.3 g (118 mmol) of 2-aminopyridine were dissolved in 200 ml of isopropanol at 40° C. The solution was admixed with 3.96 ml (48 mmol) of concentrated hydrochloric acid within 5 minutes (min) and stirred for a further 30 min. The suspension was cooled to 10° C. and the crystallized product was filtered off.
