Reaction Steps

To a solution of tert-butyl trans-4-((6-(methylamino)-3-phenyl-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)cyclohexylcarbamate (0.082 g, 0.19 mmol) in methylene chloride (3 mL) was added trifluoroacidic acid (0.60 mL). The reaction mixture was stirred at room temperature for 2 h, concentrated and basified by a 7.0 M aqueous solution of ammonia to pH 12. After evaporation, the residue was purified by Isco to provide 1-((trans-4-aminocyclohexyl)methyl)-N-methyl-3-phenyl-1H-pyrazolo[3,4-d]pyrimidin-6-amine (UNC00000545A) (0.051 g, 80%) as a white solid. 1H NMR (400 MHz, CD3OD) δ 8.94 (s, 1H), 7.94-7.83 (m, 2H), 7.55-7.44 (m, 2H), 7.44-7.36 (m, 1H), 4.16 (d, J=7.5 Hz, 2H), 3.06-2.91 (m, 1H), 2.99 (s, 3H), 2.13-1.93 (m, 3H), 1.78 (d, J=12.7 Hz, 2H), 1.45-1.14 (m, 4H); 13C NMR (100 MHz, CD3OD) δ 162.87, 157.72, 154.93, 145.73, 133.64, 130.01, 129.95, 127.97, 52.28, 51.32, 49.64, 49.43, 49.21, 49.00, 48.79, 48.57, 48.36, 38.38, 31.91, 29.71, 28.52; MS m/z 337.3 [M+H]+.
