Reaction Steps

To a solution of 2 g of 4,5,6,7-tetrahydro-8H-thieno[2,3-c]azepin-8-one and 2 g of chloroacetyl chloride in 25 ml of dichloromethane was added 4.8 g of aluminum chloride. The mixture was stirred for 30 minutes, refluxed under heating for an hour and then poured into water. The precipitated crystals were collected by filtration and washed with isopropyl alcohol to give 2 g of 2-chloroacetyl-4,5,6,7-tetrahydro-8H-thieno[2,3-c]azepin-8-one, m.p. 221°-223° C. (decomposition).
