Procedure

A mixture of 3.1 g of 6-fluoro-3-(1-methyl-4-piperidinyl)-1H-indazole and 8 ml of benzoyl chloride was heated at 100° C. in a steam bath for 8 hrs. After cooling, ether was added and the solid was collected. The solid was treated with ammonium hydroxide solution to give an oil. The oil was dissolved in 300 ml of ether, stirred and 1.2 g of fumaric acid was added. After four hrs at ambient temperature, the fumarate salt was collected. Recrystallization from ethanol-ether yielded 3.0 g (50.9%) of product, mp 180°-182° C.
