실험 절차

1.1 g of 7-chloro-5-(o-chlorophenyl)-1,3-dihydro-2H-thieno[2,3-e]-1,4-diazepine-2-thione are refluxed for 8 hours with 1.5 g of glycolic acid hydrazide in absolute butanol. The solvent is then distilled off and the residue recrystallized from ethyl acetate containing active carbon to yield 2-chloro-4-(o-chlorophenyl)-6H-thieno[3,2-f]-s-triazolo[4,3-a][1,4]diazepine-9-methanol, melting point 219°-221° C.
