실험 절차
N,N-diisopropylethylamine (0.22 ml, 1.24 mmol) was added to a solution of N-(3-chloro-2-fluorophenyl)-6-(chloromethyl)-7-methoxyquinazolin-4-amine (160 mg, 0.41 mmol prepared as described in Example 62) in dimethylformamide (1 ml). After 5 minutes of stirring, the reaction mixture became homogeneous and tert-butyl 3-(aminocarbonyl)-3-(methylamino)azetidine-1-carboxylate (98 mg, 0.43 mmol) was added. After 30 minutes of stirring at 80° C., the reaction mixture was cooled down to room temperature, water was added and the aqueous layer was extracted with ethyl acetate (×2). The combined organics were dried over magnesium sulfate, filtered and concentrated under reduced pressure. The residues were purified by column chromatography on silica eluting with increasingly polar mixtures of methanol/dichloromethane (0/100-5/95) to give tert-butyl 3-(aminocarbonyl)-3-[({4-[(3-chloro-2-fluorophenyl)amino]-7-methoxyquinazolin-6-yl}methyl)(methyl)amino]azetidine-1-carboxylate as a yellow solid, (100 mg, 44%); 1H NMR Spectrum: (CDCl3) 1.46 (s, 9H), 2.39 (s, 3H), 3.82 (s, 2H), 3.99 (s, 3H), 4.17 (d, 2H), 4.25 (brd, 2H), 5.47 (brs, 1H), 6.79 (brs, 1H), 7.17 (m, 2H), 7.29 (s, 1H), 7.66 (brs, 1H), 7.83 (s, 1H), 8.49 (brs, 1H), 8.75 (s, 1H); Mass Spectrum: (M+H)+ 545.
