実験手順

A reaction mixture of methyl 5-{3-(cyanomethyl)-3-[4-(1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-pyrrolo[2,3-b]pyridin-4-yl)-1H-pyrazol-1-yl]azetidin-1-yl}pyrazine-2-carboxylate (0.13 g, 0.24 mmol), lithium hydroxide monohydrate (0.025 g, 0.60 mmol) in methanol (4.0 mL), THF (2.0 mL) and water (1.0 mL) was stirred at 40° C. for 3 h. The mixture was adjusted to pH=4 with 2.0 N HCl aqueous solution, and concentrated under reduced pressure to remove MeOH and THF. The precipitate formed was filtered, washed with water and ether, and dried in vacuum to afford the desired product (0.100 g, 79%). LCMS (M+H)+: m/z=531.4.
