Reaktionsschritte

191 ml of a solution of 1.4M of n-butyllithium per liter of hexane were added under argon at 0° C. to a solution of 19.05 g of N-(2-thiazolyl)-acetamide in 580 ml of tetrahydrofuran and then a solution of 14.04 g of the product of Step A in 100 ml of tetrahydrofuran were added thereto at -70° to -75° C. The mixture was poured into a mixture of water and 2N hydrochloric acid and the mixture was vacuum filtered. The product was washed with water and dried under reduced pressure to obtain 16.6 g of 2-[(2-chloro-1-oxo-propyl)-amino]-β-oxo-N-(2-thiazolyl)-benzene-propanamide melting at 204° C.
