Procedure

A mixture of 3-{4[4,4-bis(4-fluorophenyl)butyl]-1-piperazinyl}-6-fluoro-1H-indazole (3.7 g, 0.008 mol) of Example 36 and benzoyl chloride (18.2 g, 0.129 mol) was warmed on a steam bath under N2 for 2 hours. The reaction was cooled to room temperature and the only residue was diluted with ether. The product was isolated by vacuum filtration and the filter cake was washed well with ether affording 4.2 g of a solid. The product was recrystallized twice from ethanol to provide 2.7 g (50%) of 1-benzoyl-3-{4-[4,4-bis(4-fluorophenyl)butyl]-1-piperazinyl-6-fluoro-1H-indazole hydrochloride, mp 236°-238° C.
