Reaction Steps

To a solution of 9.3 g of 2-amino-4-thiazolyl acetic acid ethyl ester in 50 ml of N,N-dimethylacetamide is added under ice-cooling 7.91 g of chloroacetyl chloride with stirring. The mixture is stirred for one hour at room temperature, to which is added 300 ml of water. Then the resulting crystals are collected by filtration. The crystals are washed with water and ether in this order, followed by drying over phosphorus pentachloride to yield 12.1 g (92%) of 2-chloroacetamido-4-thiazolyl-acetic acid ethyl ester, m.p. 145°-146° C.
