Reaction Steps

To a solution of tert-butyl 3-(3-{1-[4-amino-3-(difluoromethyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]ethyl}-5-cyano-2-methoxy-6-methylphenyl)azetidine-1-carboxylate (0.20 g, 0.39 mmol) in methylene chloride (5 mL) was added 4.0 M hydrogen chloride in 1,4-dioxane (0.60 mL, 2.4 mmol). The resulting mixture was stirred at room temp for 3.5 h. The solvents were evaporated and the residue dried in vacuo to give 0.23 g of the product as the HCl salt. LCMS calculated for C20H22F2N7O (M+H)+: m/z=414.2; Found: 414.1.
