실험 절차

10g (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. Yield: 8.6 g (70% of theory) 1H NMR: 3.62 (s, 3H); 7.08 (d, 1H); 7.32 (d, 1H); 7.45-7.60 (m, 3H); 8.02 (d, 2H); 8.22 (d, 1 H); 9.28 (s, 1 H); 10.45 (d, 1 H)
