Procedure

To a solution of tert-butyl 3-{3-[1-(4-amino-3-vinyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)ethyl]-5-chloro-6-fluoro-2-methoxyphenyl}azetidine-1-carboxylate (340 mg, 0.680 mmol) in tert-butyl alcohol (5 mL) was added N-methylmorpholine N-oxide (87 mg, 0.74 mmol) and water (2.1 mL). To this solution was then added 4% osmium tetraoxide (0.21 mL, 0.034 mmol). After stirring for 3 h, another equivalent of N-methylmorpholine N-oxide was added. The reaction was stirred at room temperature overnight. The solution was diluted with water, and extracted with EtOAc. The combined organic layers were dried over MgSO4, filtered and concentrated to give the crude product (0.4 g, 100%) which was used directly in the next step. LCMS calculated for C24H31 ClFN6O5 (M+H)+: m/z=537.2; Found: 537.2.
