Reaction Steps
To a solution of tert-butyl 4-(cyanomethyl)-4-[4-(methoxycarbonyl)-3-(phenylamino)-1H-pyrazol-1-yl]piperidine-1-carboxylate (0.12 g, 0.27 mmol) in THF (1.8 mL) was added MeOH (1 mL), and 1M aqueous NaOH (0.82 mL, 0.82 mmol). The mixture was heated to 50° C. for 2 hours. The mixture was then cooled to ambient temperature and acidified to pH 3-4 with 1N aqueous HCl. The mixture was extracted with EtOAc (2×). The combined organic extracts were washed with brine, dried over anhydrous MgSO4, filtered, and concentrated in vacuo. The residue was purified by MPLC on silica gel (using a gradient elution of 0-10% MeOH/DCM) to afford the title compound.
