Reaction Steps

To a solution of 5.8 g of 5-o-chlorophenyl-7-ethyl-2,3-dihydro-1H-thieno[2,3-e][1,4]diazepine in 50 ml of pyridine is added 4.5 g of 3-morpholinopropylcarbamoyl chloride and stirred for 24 hours at 60° C. Then pyridine is evaporated under reduced pressure, and to the residue is added acetone to crystallize. The crude crystals obtained are recrystallized from ethanol to give 5-o-chlorophenyl-7-ethyl-1-(3-morpholinopropylcarbamoyl)-2,3-dihydro-1H-thieno[2,3-e][1,4]diazepine dihydrochloride as yellow crystals, melting at 225°-238° C with decomposition.
