Procedure

3-((1E)-2-Phenylvinyl)-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carbonitrile (0.275 g, 0.83 mmol) was dissolved in ethyl acetate (20 mL). The flask was purged with nitrogen, then hydrogen. To this solution was added palladium on carbon (10 weight %, 14 mg). The mixture was stirred under an atmosphere of hydrogen for 5 hours. The catalyst was filtered and washed with small portions of ethyl acetate (5 mL). The filtrate was concentrated under reduced pressure resulting in the title compound (oil solidified under vacuum) (0.117 g, 84% yield): ES-MS (m/z) 332 [M+1]+.
