실험 절차

To a solution of 1-(5-tert-butylisoxazol-3-yl)-3-[3-(7-ethoxy-6-methoxyquinazolin-4-yloxy)phenyl]urea in MeOH and CH2Cl2 was added 1.0 M HCl in ethyl ether (2 equivalents). After solvent was concentrated under reduced pressure, to the residue was added ethyl ether and a white solid was formed. It was filtered, washed with ethyl ether, and dried under vacuum with P2O5 to afford 1-(5-tert-butylisoxazol-3-yl)-3-[3-(7-ethoxy-6-methoxyquinazolin-4-yloxy)phenyl]urea hydrochloride as a white solid (0.067 g, 16%). 1H NMR (300 MHz, DMSO-d6) δ 9.64 (s, 1H), 9.19 (s, 1H), 8.62 (s, 1H), 7.59 (s, 2H), 7.40 (m, 2H), 7.26 (d, 1H), 6.98 (d, 1H), 6.48 (s, 1H), 4.27 (q, 2H), 3.99 (s, 3H), 1.44 (t, 3H), 1.27 (s, 9H); LC-MS (ESI) m/z 478 (M+H)+.
