Procedure

A mixture of lithium hydroxide monohydrate (0.87 g, 21 mmol) and methyl 5-{3-(cyanomethyl)-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}pyridine-2-carboxylate (3.70 g, 6.79 mmol) in methanol (10.0 mL) and water (5.0 mL) was stirred at room temperature overnight. The mixture was adjusted to pH 3 with aqueous HCl (1.0 N), and concentrated under reduced pressure to remove methanol. The solid formed was filtered and washed with water, and dried under reduced pressure to afford the crude product. LCMS (M+H)+: m/z=531.1.
