실험 절차

To 2.0 g (0.007 mole) of 2-(2-chloroethyl)-2,3-dihydro-4-methyl-7-nitro-1,4-benzoxazepin-5(4H)-one in 35 ml of acetonitrile was added 1.0 g (0.0023 mole) of phosphorus pentasulfide and the mixture heated to reflux for 2 hr. Another 0.4 g (0.001 mole) of phosphorus pentasulfide was added and heating continued for 2 hr. After cooling, the reaction mixture was diluted with 100 ml of toluene and filtered. The filtrate was washed with 3×50 ml of saturated sodium bicarbonate and 100 ml of water, dried over sodium sulfate, filtered, charcoaled, filtered, and concentrated by rotary evaporation. The crude oil was crystallized from isopropyl ether/toluene to give 1.2 g (57%) of yellow crystals, m.p. 153°-155° C.
