実験手順

Into a 10 mL sealed tube, was placed a solution of 3-[(3R)-3-[4-amino-3-[4-(2,5-difluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidin-1-yl]-3-oxopropanenitrile (150 mg, 0.31 mmol, 1.00 equiv) in methanol (5 mL), piperidine (78 mg, 0.92 mmol, 3.0 equiv), and cyclopropanecarbaldehyde (64 mg, 0.91 mmol, 3.0 equiv). The resulting solution was stirred for 12 h at 25° C. and then concentrated under vacuum. The resulting solution was diluted with dichloromethane and washed with saturated aqueous ammonium chloride, water and brine. The organics were dried over anhydrous sodium sulfate and concentrated. The residue was loaded onto a silica gel column and eluted with dichloromethane/methanol (20/1) to give 38 mg (23%) of 2-[[(3R)-3-[4-amino-3-[4-(2,5-difluorophenoxy)phenyl]-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidin-1-yl]carbonyl]-3-cyclopropylprop-2-enenitrile as a white solid. LC-MS (ES, m/z): 542 [M+H], H-NMR (CDCl3, ppm): δ8.51 (s,1H); δ7.66 (d,2H); δ7.12 (m,3H); δ6.88 (m,2H); δ6.51 (d,1H); δ5.57 (s,2H); δ4.95 (m,1H); δ4.82 (m,1H); δ4.23 (m,1H); δ3.65 (m,1H); δ3.28 (m,1H); δ2.33 (m,2H); δ2.01 (m,2H); δ1.83 (m 1H); δ1.20 (m,2H); δ0.78 (m,2H).
