실험 절차

A mixture of 10 g. (35 mmole) of 7-chloro-1,3-dihydro-1-methyl-5-phenyl-2H-1,4-benzodiazepin-2-one, 10 g. of aluminum chloride, and 200 ml. of dried benzene was treated with 30 ml. of 1-chloro-2,3-epoxypropane in 100 ml. of benzene. The reaction mixture was stirred overnight. Work-up as in Method A, Example 5, above gave 32 g. of a crude oil. The oil was dissolved in benzene, filtered over Florisil, evaporated to dryness and crystallized from ether-petroleum ether to give the above-titled product as colorless needles, m.p. 140°-142°.
