Procedure

To a solution of methyl 4-{N-[3-(4-methoxyphenyl)-1-perhydro-2H-pyran-2-yl-1H-indazol-5-yl]carbamoyl}benzoate (0.099 g, 0.20 mmol) in anhydrous tetrahydrofuran (5 mL), 6.0N aqueous HCl was added (5 mL). The solution was stirred at room temperature for 48 hours. The reaction mixture was then neutralized with saturated aqueous sodium bicarbonate and the organic layer was extracted with ethyl acetate (10 mL, 3 times). The organic layer was dried over Na2SO4 and evaporated to dryness to afford the title compound (0.081 g, quantitative yield): ES-MS (m/z) 402 [M+1]+.
