Diisopropylethylamine → 2-{2-[4-Amino-5-(2-fluoro-4-phenoxy-phenyl)-pyrrolo[2,3-d]pyrimidin-7-ylmethyl]-pyrrolidine-1-carbonyl}-3-cyclopropyl-acrylonitrile

Participants

Reaction Steps

To a mixture of 5-(2-fluoro-4-phenoxy-phenyl)-7-pyrrolidin-2-ylmethyl-7H-pyrrolo[2,3-d]pyrimidin-4-ylamine (100 mg, 0.25 mmol, 1.0 eq), 2-cyano-3-cyclopropyl-acrylic acid (42 mg, 0.3 mmol, 1.2 eq) and DIEA (97 mg, 0.75 mmol, 3.0 eq) in 10 ml of DCM was added HATU (145 mg, 0.38 mmol, 1.5 eq). The mixture was stirred for 4 h at RT under N2. LCMS showed the reaction was completed. The reaction mixture was concentrated and purified by Pre-TLC to provide 71 mg (54%) of the title compound. LCMS: m/z 523.2 (M+H)+. 1HNMR (400 MHz, DMSO-d6): δ 0.866˜0.920 (m, 2H), 1.177˜1.194 (m, 2H), 1.569 (m, 1H), 1.721 (m, 2H), 1.883 (m, 2H), 3.200 (m, 2H), 3.511 (m, 1H), 4.360˜4.475 (m, 2H), 6.125 (m, 2H), 6.642˜6.664 (m, 1H), 6.898˜6.920 (m, 1H), 6.977˜7.010 (m, 1H), 7.150˜7.232 (m, 4H), 7.371˜7.471 (m, 3H) and 8.131 (m, 1H).
