Procedure

Into a 50-mL round-bottom flask, was placed N-(4-[4-amino-1-[1-(2-cyanoacetyl)-piperidin-3-yl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl]phenyl)-4-(trifluoromethyl)benzamide (130 mg, 0.24 mmol, 1.00 equiv), 2,2-dimethylpropanal (2 mL), piperidine (1 mL), and methanol (30 mL). The resulting solution was stirred for 24 h at 30° C. in an oil bath. The resulting mixture was concentrated under vacuum and residue was loaded onto a silica gel column and eluted with dichloromethane/methanol (50/1 to give 40 mg (27%) of N-[4-(4-amino-1-[1-[2-cyano-2-(2,2-dimethylpropylidene)acetyl]piperidin-3-yl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl)phenyl]-4-(trifluoromethyl)benzamide as a white solid. MS (ESI, pos. ion) m/z: 617 (M+1), 1HNMR (300 MHz, CDCl3, ppm), 8.364 (1H, s), 8.212 (1H, s), 8.086˜8.059 (2H, t), 7.929˜7.901 (2H, d, J=8.4), 7.827˜7.800 (2H, d, J=8.1), 7.742˜7.715 (2H, d, J=8.1), 6.963 (1H, s), 6.3 (2H, s), 5.031˜4.934 (1H, m), 4.8˜3.05 (4H, m), 2.738˜2.067 (5H, m), 1.274 (9H, s).
