Hydrochloric Acid → 6-(4-Amino-2-fluorophenoxy)-N-(4-(benzyloxy)phenyl)pyrimidin-4-amine

Participants

Reaction Steps

A mixture of N-(4-(6-(4-(benzyloxy)phenylamino)pyrimidin-4-yloxy)-3-fluorophenyl)acetamide (150 mg, 0.34 mmol), 6 M HCl (0.5 mL) and MeOH (3 mL) was heated at reflux for 2 h. The mixture was concentrated to remove the MeOH and the residue treated with saturated NaHCO3 solution and extracted with EtOAc. The organic phase was dried (MgSO4) and concentrated in vacuo to give the title compound (123 mg, 90%) as a pink solid. 1H NMR (DMSO-d6): δ 9.37 (s, 1H), 8.24 (s, 1H), 7.46-7.31 (m, 7H), 6.99-6.92 (m, 3H), 6.48 (dd, 1H, J=12.5, 2.7 Hz), 6.39 (dd, 1H, J=8.6, 2.7 Hz), 5.97 (s, 1H), 5.39 (br s, 2H), 5.08 (s, 2H); MS (ESI+) m/z 403.09 (M+H)+.
