Reaction Steps

Diisopropylethylamine (0.11 ml, 0.63 mmol) and then HATU (95 mg, 0.25 mmol) were added to a solution of acetic acid (18 μl, 0.31 mmol) in dichloromethane (1 ml). After 10 minutes, the hydrochloride salt of 3-[({4-[(3-chloro-2-fluorophenyl)amino]-7-methoxyquinazolin-6-yl}methyl)(methyl)amino]azetidine-3-carboxamide (100 mg, 0.21 mmol Example 74) was added and the mixture stirred overnight at room temperature. After removal of the solvent, the resulting product was dissolved in dimethylformamide and purified on preparative HPLC (standard basic conditions) to give the title product as a powder (52 mg, 51%); 1H NMR Spectrum: (CDCl3) 1.92 (d, 3H), 2.38 (s, 3H), 3.70 (d, 1H), 3.83 (d, 1H), 3.98 (s, 3H), 4.18-4.27 (m, 3H), 4.55 (d, 1H), 5.80 (brs, 1H), 6.94 (brs, 1H), 7.15 (m, 2H), 7.29 (s, 1H), 7.96 (brs, 2H), 8.34 (brs, 1H), 8.72 (s, 1H); Mass Spectrum: (M+H)+ 487.
