Procedure

To a suspension of 0.246 g. of 4-ethyl-1,3,4,9-tetrahydro-10H-thieno[3,4-b] [1,5]benzodiazepin-10-one in 2 ml. of dry pyridine is added in portions a total of 0.133 g. of N-chlorosuccinimide. The resulting solution is heated on a steam bath for 15 minutes, cooled and diluted with water. The solid is collected and recrystallized from methanol-water to give off-white crystals, m.p. 201°-202°C.
