실험 절차

A mixture of 23.6 parts of 2,3-dihydro-4-phenyl-1H-1,5-benzodiazepin-2-one and 24.4 parts of phosphorus pentasulfide in 400 parts by volume of pyridine is stirred at reflux temperature for one hour. This solution is then added dropwise with stirring to about 2000 parts by volume of 60° C. warm water. The solid which forms is separated by filtration, washed with water and dried in air overnight. The product thus obtained is recrystallized from ethyl acetate to give, as beige crystals, 2,3-dihydro-4-phenyl-1H-1,5-benzodiazepine-2-thione. This product has the formula ##STR12##
