1-(4-(6-(4-Methoxybenzylamino)pyrimidin-4-yloxy)-3-fluorophenyl)-3-(2-(4-fluorophenyl)acetyl)urea → 1-(4-(2-(4-Methoxybenzylamino)pyrimidin-4-yloxy)-3-fluorophenyl)-3-(2-(4-fluorophenyl)acetyl)urea

Participants

Reaction Steps

A solution of N-(4-methoxybenzyl)-4-(4-amino-2-fluorophenoxy)pyrimidin-2-amine (Compound C of Example 14, 34 mg, 0.10 mmol) in THF (1 ml) was treated with 0.36 M 2-(4-fluorophenyl)acetyl isocyanate in toluene (Compound D of Example 11, 0.31 mL, 0.11 mmol) and the mixture stirred at RT for 1 h. The mixture was concentrated in vacuo and the solid obtained was triturated first with 3:1 isopropyl ether/EtOAc and then CH2Cl2 to give the title compound (32 mg, 62%) as an off-white solid. 1H NMR (DMSO-d6) δ 10.47 (s, 1H), 10.26 (s, 1H), 8.15 (s, 1H), 7.76 (d, 1H, J=12.6 Hz), 7.61 (dd, 3H, J=9.1, 5.0 Hz), 7.29 (s, 2H), 7.31-7.21 (m, 3H), 6.81 (s, 3H), 6.24 (s, 1H), 4.32 (s, 1H), 3.96 (s, 1H), 3.68 (s, 3H), 3.48 (s, 2H); MS (ESI+) m/z 520.14 (M+H)+.
