Procedure

Into a 50 mL round-bottom flask, was placed a solution of 3-[(2R)-2-([4-amino-3-[4-(2-fluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]methyl)pyrrolidin-1-yl]-3-oxopropanenitrile (50 mg, 0.11 mmol, 1.00 equiv) in methanol (10 mL), piperidine (50 mg, 0.59 mmol, 6.73 equiv), and cyclopropanecarbaldehyde (50 mg, 0.71 mmol, 5.54 equiv). The resulting solution was stirred for 1 h at room temperature and then concentrated under vacuum. The residue was loaded onto a silica gel column and eluted with dichloromethane/methanol (100:1, 50:1) to give 0.0179 g (32%) of the title compounds as an off-white solid. LC-MS (ES, m/z): 524 [M+H]+, 1HNMR (300 MHz, CDCl3, ppm) 8.396 (1H, s), 7.689˜7.628 (2H, m), 7.284˜7.085 (6H, m), 6.825˜6.798 (1H, d); 5.663 (2H, s); 4.868 (1H, d); 4.676 (2H, d); 3.708˜3.470 (2H, m); 2.060˜1.980 (5H, m); 1.226 (2H, t); 0.873 (2H, s).
