Reaction Steps

To a solution of 3-(3,4-dimethoxyphenyl)-1-perhydro-2H-pyran-2-yl-1H-indazole-5-carbonitrile (550 mg, 1.51 mmol) in methanol (30 mL) was added 6 N HCl (30 mL). The solution was stirred at room temperature for 3 hours when water (80 mL) was added and the suspension filtered to give after drying, the title compound (390 mg, 93% yield). ES-MS (m/z) 280 [M+1]+.
