실험 절차

A solution of 2 g of ethyl 4,5-dihydroimidazo[1,2-a]quinoxaline-2-carboxylate in 20 ml of dry dimethylformamide was treated with 2 ml of chloroacetyl chloride and the mixture was stirred overnight. A white solid settled out and was filtered off and crystallized from ethanol to obtain 2.27 g (86% yield) of ethyl 4,5-dihydro-5-chloroacetylimidazo[1,2-a]quinoxaline-2-carboxylate melting at 178°-83° C.
