Reaction Steps

5-[2-(3-Hydroxy-4-methoxy-phenylamino)-pyrimidin-4-yl]-thiophene-2-carboxylic acid (1-phenyl-ethyl)-amide (35 mg, 78 μmol), dimethylaminoethanol (26 μL, 156 μmol), and triphenylphosphine (41 mg, 156 μmol) were dissolved in 0.14 mL THF and cooled to 0° C. Diisopropyldiazodicarboxylate (31 μL, 156 μmol) were added dropwise. The reaction mixture was slowly warmed to room temperature and stirred overnight. The crude product was diluted with DMSO and purified by mass triggered reverse phase HPLC to afford 0.3 mg of pure 5-{2-[3-(2-Dimethylamino-ethoxy)-4-methoxy-phenylamino]-pyrimidin-4-yl}-thiophene-2-carboxylic acid (1-phenyl-ethyl)-amide (0.6 μmol, 1%). 1H NMR (500 MHz, DMSO-d6) δ 9.49 (s, 1H), 8.94 (d, J=8 Hz, 1H), 8.47 (d, J=5 Hz, 1H), 7.98 (d, J=4 Hz, 1H), 7.93 (d, J=4 Hz, 1H), 7.57 (m, 1H), 7.38 (m, 2H), 7.31 (m, 4H), 7.23 (m, 1H), 6.88 (d, J=8 Hz, 1H), 5.12 (quintet, J=7.5 Hz, 1H), 4.05 (t, J=6 Hz, 2H), 3.71 (s, 3H), 2.64 (t, J=6 Hz, 2H), 2.17 (s, 6H), 1.48 (d, J=6.5 Hz, 3H). MS: m/z 518 (M+H+).
