실험 절차

A 1.08 g. portion of thieno[3,4-b][1,5]benzoxazepin-10(9H)-one and 1.15 g. of phosphorus pentachloride in 22 ml. of dry toluene are reacted as described in Example 1, giving 10-chloro-thieno[3,4-b][1,5]benzoxazepine. To this is added 10 ml. of toluene, 7.2 g. of N-ethylpiperazine and 25 ml. of triethylamine. The mixture is heated overnight at 100° C. and concentrated to dryness. The residue is treated as described in Example 3 providing the base compound as a foam which is converted to the fumarate, m.p. 215°-217° C.
