Reaction Steps

A solution of tert-butyl 6-(2-(2-amino-4-(2-fluoro-4-(3-(2-(4-fluorophenyl)acetyl)ureido)phenoxy)pyridin-3-yl)ethynyl)pyridin-3-ylcarbamate (23 mg, 0.037 mmol) in CH2Cl2 (2 mL) and treated with TFA (0.5 mL) and stirred at RT for 1 h. The mixture was concentrated in vacuo and the crude product purified by preparative HPLC (Column B) and converted to its hydrochloride salt (11 mg, 52%) in the same manner as Step E of Example 36. 1H NMR (DMSO-d6) δ 11.05 (s, 1H), 10.62 (s, 1H), 8.05 (s, 1H), 7.97 (d, 1H, J=2.7 Hz), 7.94 (d, 1H, J=7.1 Hz), 7.82 (d, 1H, J=12.1 Hz), 7.66 (d, 1H, J=8.8 Hz), 7.45-7.45 (m, 2H), 7.35 (dd, 2H, J=8.2, 5.5 Hz), 7.20 (d, 1H, J=6.6 Hz), 7.16 (t, 2H, J=8.8 Hz), 6.24 (d, 1H, J=6.6 Hz), 3.74 (s, 2H); MS(ESI+): m/z 515.19 (M+H)+.
