4-[(2-Chloromethyl-quinazolin-4-yl)-methyl-amino]-phenol hydrochloride: To 4-chloro-2-chloromethyl-quinazoline (200 mg) suspended in isopropanol (3 ml) was added 4-methylamino-phenol (389 mg) and followed by HCl (12 M, 2 drops). The reaction was stirred overnight at room temperature. The resulting precipitate was filtered to give 391 mg of (2-chloromethyl-quinazolin-4-yl)-(4-methoxy-phenyl)-methyl-amine as the hydrochloride salt. 1H NMR (MeOH-d4) δ 7.28 (m, 4H), 6.90 (m, 4H), 4.8 (s, 2H), 3.8 (s, 3H); LC-MS (ESI+; 332 ([M+H]+)).
