Reaction Steps

A mixture of 6.3 g of 4-(chloroacetyl)-4,5-dihydro-7-[3-(trifluoromethyl)phenyl]pyrazolo[1,5-a]pyrimidine-3-carbonitrile, 3.7 of 2-fluorobenzyl piperazine and 4.1 g of triethylamine in 250 ml of tetrahydrofuran was stirred under reflux for 18 hours, then cooled and diluted with 500 ml of water. The resulting solid was collected, washed with water, dried, then heated to solution in 200 ml of ethyl acetate, filtered and refrigerated. The resulting solid was collected, washed with hexane and dried, giving 7.1 g of the desired product, mp 188°-190° C.
