実験手順

To a solution of (+/−)-trans-(2,3)-methyl 3-((5-chloro-2-(5-fluoro-1-trityl-1H-pyrazolo[3,4-b]pyridin-3-yl)pyrimidin-4-yl)amino)bicyclo[2.2.2]octane-2-carboxylate, 38, (0.85 g, 1.26 mmol) in CH2Cl2 (42.5 mL) at room temperature was added Et3SiH (1.00 mL, 6.32 mmol) followed by trifluoroacetic acid (0.97 mL, 12.60 mmol). The reaction was stirred at room temperature. After the reaction was complete, as judged by LC-MS, the solution was concentrated in vacuo. Careful flash chromatography (SiO2, 0-7% MeOH—CH2Cl2, gradient elution) provided the desired product (373 mg, 66% yield)L 1H NMR (400 MHz, MeOD) δ 8.66 (dd, J=8.3, 2.5 Hz, 1H), 8.53 (s, 1H), 8.28 (s, 1H), 5.05 (d, J=6.5 Hz, 1H), 3.69 (s, 3H), 2.95 (d, J=6.8 Hz, 1H), 2.09 (s, 1H), 1.98 (s, 1H), 1.96-1.79 (m, 3H), 1.77-1.61 (m, 3H), 1.61-1.45 (m, 2H); LC/MS Gradient 10-90%, 0.1% formic 5 min, C18/ACN, RT=2.55 min, (M+H) 431.14.
