Morpholine → N-{5-[2-(4-Fluoro-phenylamino)-pyrimidin-4-yl]-4-methyl-thiazol-2-yl}-3-morpholin-4-yl-propionamide

Participants

Reaction Steps

A solution of 3-bromo-N-{5-[2-(4-fluoro-phenylamino)-pyrimidin-4-yl]-4-methyl-thiazol-2-yl}-propionamide (20 mg, 0.046 mmol) and morpholine (8 μL, 0.092 mmol,) in DMF (2 mL) was stirred at room temperature for 2 h. The reaction mixture was purified by preparative RP-HPLC (0-60% MeCN in 0.1% aq CF3COOH over 40 min, 9 mL/min) to afford the title compound as a pale solid. Anal. RP-HPLC: tR=13.3 min (0-60% MeCN in 0.1% aq CF3COOH over 20 min, 1 mL/min, purity>93%). 1H-NMR (CD3OD) δ: 2.66 (s, 3H, CH3), 3.23 (m, 2H, CH2), 3.33 (m, 2H, CH2), 3.41 (m, 4H, CH2), 3.87 (m, 2H, CH2), 4.13 (m, 2H, CH2), 7.04-7.09 (m, 3H, pyrimidinyl-H & Ph-H), 7.68 (m, 2H, Ph-H), 8.39 (d, 1H, J=5.5 Hz, pyrimidinyl-H). MS (ESI+) m/z 443.3 (C21H23FN6O2S requires 442.5).
