To a solution of tert-butyl 3-{3-[1-(4-amino-3-methyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-5-chloro-2-methoxy-6-methylphenyl}azetidine-1-carboxylate (318 mg, 0.653 mmol) (peak 1 from above) in methylene chloride (3.2 mL) was added 4.0 M hydrogen chloride in 1,4-dioxane (1.6 mL, 6.5 mmol). The resulting mixture was stirred at room temperature for 75 minutes. The solvents were evaporated and the residue dried in vacuo to give 0.30 g of the desired product as the bis-HCl salt. LCMS calculated for C19H24ClN6O (M+H)+: m/z=387.2; Found: 387.1.
