(2-Chloromethyl-quinazolin-4-yl)-(4-ethoxy-2-fluoro-phenyl)-methyl-amine: To (2-chloromethyl-quinazolin-4-yl)-(4-ethoxy-2-fluoro-phenyl)-amine hydrochloride (531 mg, 1.5 mmol) dissolved in THF at 0° C. was added methyl iodide (1.89 mL, 30.3 mmol) and sodium hydride (363 mg, 15.1 mmol). The reaction was stirred at room temperature for 4 h then warmed to room temperature for 1 h. The reaction was quenched with H2O and diluted with EtOAc. The aqueous phase was extracted with EtOAc (3×10 mL). The combined organic phases were washed with brine, dried (MgSO4), concentrated and purified by gradient MPLC (0-100%, EtOAc/hexanes, SiO2) to give 341 mg of the title compound. 1H NMR (CDCl3) δ 7.83 (d, 1H), 7.59 (t, 1H), 7.31-7.04 (m, 3H), 6.75-6.69 (m, 2H), 4.74 (s, 2H), 4.02 (q, 2H), 3.58 (s, 3H), 1.45 (t, 3H); LC-MS (ESI+; 365 ([M+H]+)).
