Procedure

Into a 10-mL round-bottom flask, was placed (R)—N-(4-[4-amino-1-[1-(2-cyanoacetyl)piperidin-3-yl]-1H-pyrazolo[3,4-d]pyrimidin-3-yl]phenyl)-4-(trifluoromethyl)-benzamide (65 mg, 0.12 mmol, 1.00 equiv), cyclopropanecarbaldehyde (16.6 mg, 0.24 mmol, 2.00 equiv), piperidine (10 mg, 0.12 mmol, 0.99 equiv), methanol (5 mL). The resulting solution was stirred for 12 h at 25° C. The resulting mixture was concentrated under vacuum and the residue was loaded onto a silica gel column and eluted with dichloromethane/methanol (50:1) to give 43 mg (60%) of (R)—N-[4-(4-amino-1-[1-[2-cyano-2-(cyclopropylmethylidene)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: 601 (M+1), 1HNMR (300 MHz, CDCl3, ppm), 8.6 (1H, s), 8.348 (1Hs), 8.065˜8.038 (2H, d, J=8.1), 7.880˜7.852 (1H, d, J=8.4), 7.768˜7.659 (4H, m), 6.532˜6.496 (1H, dJ=10.8), 5.949 (2H, s), 4.976˜4.907 (1H, m), 4.638˜3.218 (4H, m), 2.436˜1.818 (5H, m), 1.221˜1.198 (2H, m), 0.89˜0.772 (2H, m).
