反应详情

To a sealed tube was added N-{3-methyl-5-[2-(1H-pyrazol-4-yl)-1,3-thiazol-5-yl]phenyl}-4-(trifluoromethyl)pyrimidin-2-amine (38.0 mg, 0.095 mmol), DMF (950 μL, 0.1 M) and NaH (15.0 mg, 0.380 mmol, 60% wt). The reaction was allowed to age for 20 minutes. Next was added 2-bromo ethanol (11.8 mg, 0.095 mmol) and the reaction was allowed to stir at rt for 4 hours. The completed reaction was quenched with H2O (100 μL) and was concentrated in vacuo. Purification by reverse phase preparative HPLC (0:100 to 95:5 acetonitrile:water: 0.1% v/v formic acid modifier) to afford the title product (2.8 mg, 0.0057 mmol, 6.0%). MS ESI: [M+H]+ m/z 447.1. 1H NMR (600 MHz, DMSO) δ 10.24 (s, 1H), 8.82 (d, J=4.9, 1H), 8.28 (s, 1H), 8.01 (s, 1H), 7.97 (s, 1H), 7.91 (s, 1H), 7.44 (s, 1H), 7.26 (d, J=4.9, 1H), 7.16 (s, 1H), 4.18 (t, J=5.5, 2H), 3.74 (s, 2H), 2.30 (s, 3H). rhSTK activity=+++
