Procedure

A mixture of N1-{4-[4-amino-1-(4-hydroxy-2-cyclopentenyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-2-fluoro-4-trifluoromethylbenzamide (0.10 g, 0.19 mmol) and 10% palladium on carbon (0.03 g) in ethanol (10 mL) was stirred at ambient temperature under one atmosphere of hydrogen overnight. The mixture was filtered and the filtrate was purified by preparative HPLC to yield N1-{4-[4-amino-1-(3-hydroxycyclopentyl)-1H-pyrazolo[3,4-d]pyrimidin-3-yl]-2-methoxyphenyl}-2-fluoro-4-trifluoromethylbenzamide (0.07 g, 0.13 mmol) as a white sold: 1H NMR (DMSO-d6, 400 MHz) δ 9.91 (dd, 1H), 8.31(d, 1H), 8.24 (s, 1H), 8.00 (t, 1H), 7.89 (d, 1H), 7.75 (d, 1H), 7.34 (s, 1H), 7.30 (d, 1H), 6.90 (br, 2H), 5.17 (m, 1H), 4.97 (m, 1H), 4.22 (m, 1H), 3.94 (s, 3H), 1.79-2.41 (m, 6H); MS: MH+ 531.
