Participants

Reaction Steps

11.9 G. of 1-[3-chloro-7-trifluoromethyl-dibenz[b,f]oxepin-10-yl]-4-methyl-piperazine was reduced with sodium borohydride in glacial acetic acid in a manner analogous to that described in Example 14, and there is obtained crude 1-[3-chloro-10,11-dihydro-7-trifluoromethyl-dibenz[b,f]oxepin-10-yl]-4-methylpiperazine which is recrystallized from isopropanol and melts at 110° C. The dihydrochloride, prepared in ethanol, melts at 219°-222° C. (with decomposition).
