Procedure

A mixture of 4.0 g of 3-(1-methyl-4-piperidinyl)-1H-indazole, 2.7 ml of 2-furoyl chloride (95% pure) and 60 ml of chloroform was refluxed for 3 hrs. The mixture was filtered. The filtrate was evaporated under reduced pressure, the residue was triturated with ethyl acetate and the solid was collected. The solid and filtrate were combined and recrystallized twice from ethanol to yield 3.3 g (51.5%) of product, mp 268°-270° C.
