Procedure
A mixture of 3.3 g of 4-(chloroacetyl)4,5-dihydro-6-ethyl-7-[3-(trifluoromethyl)phenyl]pyrazolo[1,5-a]pyrimidine-3-carbonitrile, 1.6 ml of 1-benzylpiperazine and 1 g. of sodium carbonate in 110 ml of toluene was stirred and refluxed for 18 hours. The mixture was treated with 10 ml of 5N sodium hydroxide and the organic phase was separated, dried over sodium sulfate and evaporated to give a dark oil. This was dissolved in ether and combined with ethanolic hydrogen chloride to give a white solid and this solid was recrystallized from acetonitrile to give 3.4 g to the title compound, m.p. 184°-186° C.
