Procedure

Into a 10-mL round-bottom flask, was placed 3-[(2R)-2-([4-amino-3-[4-(3-fluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl)pyrrolidin-1-yl]-3-oxopropanenitrile (150 mg, 0.32 mmol, 1.00 equiv), piperidine (27 mg, 0.32 mmol, 1.00 equiv), cyclopropanecarbaldehyde (44.5 mg, 0.63 mmol, 2.00 equiv), methanol (5 mL). The resulting solution was stirred for 12 h at 25° C. and then concentrated under vacuum. The residue was loaded on a silica gel column and eluted with dichloromethane/methanol (50/1) to give 48.5 mg (29%) of the title compound as a off-white solid. LC-MS: (ES, m/z): MS (ESI, pos. ion) m/z: 524 (M+1). 1H-NMR: (CDCl3, ppm): 1HNMR (300 MHz, CD3OD, ppm), 8.253 (1H, s), 7.686˜7.749 (2H, t), 7.363˜7.440 (1H, t), 7.185˜7.232 (2H, t), 6.833˜6.941 (3H, m), 6.450˜6.600 (1H, d), 4.301˜4.555 (3H, m), 3.604˜3.638 (2H, m), 1.868˜2.005 (5H, m), 1.200˜1.294 (3H, m), 0.798˜0.810 (2H, m).
