Reaction Steps

To a solution of ethyl 2-chloro-3-(2,6-difluorophenyl)oxirane-2-carboxylate in EtOH was added thiourea, followed by heating under reflux for 4 hours. To the reaction mixture was added ice-water, followed by addition of K2CO3 to make it basic. The solid precipitated was collected by filtration and washed with water to obtain ethyl 2-amino-5-(2,6-difluorophenyl)-1,3-thiazole-4-carboxylate as a yellow solid.
