Procedure
A 2.13 g. portion of 7-bromo-thieno[3,4-b][1,5]benzoxazepin-10(9H)-one (Example 9) and 1.5 g. of phosphorus pentachloride in 40 ml. of dry toluene are reacted as described in Example 9, giving 7-bromo-10-chloro-thieno[3,4-b][1,5]benzoxazepine which is further reacted with N-methylpiperazine in 15 ml. of dry toluene giving the base compound as a foam which is then converted to the hemifumarate, m.p. 196°-197° C.
