Versuchsvorschrift

To a mixture of (R)-3-(4-(2,3-difluorophenoxy)-2-fluorophenyl)-1-(piperidin-3-yl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (100 mg, 0.23 mmol, 1.0 eq), 2-cyano-4-methyl-pent-2-enoic acid (38 mg, 0.27 mmol, 1.2 eq) and DIEA (88 mg, 0.68 mmol, 3.0 eq) in 10 ml DCM was added HATU (130 mg, 0.34 mmol, 1.5 eq). The reaction mixture was stirred for 4 h at RT under N2. The mixture was purified by Pre-HPLC to give the title compound (25 mg 40% yield). LCMS: m/Z+ (562.2) (M+H)+1HNMR (400 MHz, CDCl3): δ 0.784˜1.186 (m, 7H), 1.765˜2.254 (m, 5H), 2.861˜4.937 (m, 4H), 6.218 (m, 0.4H), 6.857˜7.600 (m, 6H), 8.255 (s, 1H) and 9.888 (m, 1H).
