Procedure
A solution of HCl/1,4-dioxan (1/5) (2 ml) was added dropwise to a solution of tert-butyl 3-[({4-[(3-chloro-2-fluorophenyl)amino]-7-methoxyquinazolin-6-yl}methyl)(methyl)amino]-3-[(methylamino)carbonyl]azetidine-1-carboxylate (310 mg, 0.56 mmol) in 1,4-dioxan (6 ml). The reaction mixture was stirred overnight, then concentrated under reduced pressure. Three triturations in methanol/dichloromethane/diethyl ether afforded the isolation of a hydrochloride salt of 3-[({4-[(3-chloro-2-fluorophenyl)amino]-7-methoxyquinazolin-6-yl}methyl)(methyl)amino]-N-methylazetidine-3-carboxamide as a solid (336 mg, 100%). 1H NMR Spectrum: (DMSO d6) 2.16 (s, 3H), 2.71 (d, 3H), 3.70 (s, 2H), 3.97 (m, 2H), 4.03 (s, 3H), 4.13 (m, 2H), 7.37 (m, 2H), 7.55 (t, 1H), 7.66 (t, 1H), 8.31 (brs, 1H), 8.90 (brs, 2H), 9.27 (s, 1H), 9.75 (brs, 1H); Mass Spectrum: (M+H)+ 459.
