Reaction Steps

3-[3-(2-Piperidylethoxy)phenyl]-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carbonitrile (0.67 g, 1.6 mmol) was dissolved in 2 mL EtOH and the solution was cooled to 0° C. Aqueous 6 N NaOH solution (1.04 mL, 0.25 g, 6.2 mmol) and aqueous 30% H2O2 (0.7 mL, 0.21 g, 6.2 mmol) were added to the reaction mixture. The reaction mixture was warmed to room temperature and stirred for 1.5 h. The reaction was quenched by addition of 6 N HCl. The resultant solution was neutralized by addition of saturated aqueous solution of sodium bicarbonate. The solution was extracted with EtOAc, the organic layer was washed with water, brine, dried (Na2SO4) and filtered. The filtrate was concentrated to 0.61 g (87%) of the title compound obtained as a yellow solid. ES-MS (m/z) 449 [M+H]+.
