Reaction Steps

(E)-[2-(3-{4-[[Formyl-(2-morpholin-4-yl-ethyl)-amino]-(4-trifluoromethyl-phenylcarbamoyl)-methyl]-phenyl}-acryloylamino)-phenyl]-carbamic acid tert-butyl ester (300 mg, 0.432 mmol) was treated with 1.25M HCl in methanol (2.6 mL) at room temperature overnight. The reaction was quenched slowly with solid sodium bicarbonate until the pH was 6-7. The mixture was diluted in acetonitrile with a small amount of dimethylsulfoxide, passed through a 40 μm pipette filter, and then purified by preparative HPLC to obtain the desired product (58 mg, 24%). MS: calc'd 568 (MH+) exp 568 (MH+). 1H NMR (d6-DMSO, 400 MHz) δ 10.6 (broad s, 1H), 9.40 (s, 1H), 7.84 (d, 2H, J=8.4 Hz), 7.69 (d, 2H, J=8.4 Hz), 7.62 (d, 2H, J=8.0 Hz), 7.54 (d, 2H, J=8.0 Hz), 7.53 (d, 1H, J=15.6 Hz), 7.33 (d, 1H, J=7.6 Hz), 6.91 (t, 1H, J=7.6 Hz), 6.89 (d, 1H, J=15.6 Hz), 6.75 (d, 1H, J=7.2 Hz), 6.58 (t, 1H, J=7.2 Hz), 4.94 (broad s, 2H), 4.51 (broad s, 1H), 3.59 (m, 4H), 3.45 (m, 2H), 2.66 (m, 2H), 2.33 (m, 4H).
