Procedure

Acetyl chloride (7 μl, 0.094 mmol) was added to a stirred solution of 4-[({4-[(3-chloro-2-fluorophenyl)amino]-7-methoxyquinazolin-6-yl}methyl)(methyl)amino]piperidine-4-carboxamide hydrochloride (0.05 g, 0.085 mmol, prepared as described in Example 64) and triethylamine (53 μl, 0.38 mmol) in dichloromethane (1 ml) at room temperature. The reaction mixture was stirred at room temperature for 1 hour, concentrated and purified by column chromatography on silica eluting with increasingly polar mixtures of dichloromethane/methanol (100/0-90/10) to give the title product (0.039 g, 91%) as a pale yellow solid; 1H NMR Spectrum: (DMSO-d6) 1.75-1.98 (m, 2H), 2.05 (m, 5H), 2.19 (s, 3H), 3.32-3.75 (m, 6H), 3.94 (s, 3H), 7.20 (s, 1H), 7.26 (m, 2H), 7.34 (t, 1H), 7.51-7.57 (m, 2H), 8.38 (s, 1H), 8.46 (s, 1H), 9.80 (s, 1H); Mass Spectrum: (M+H)+ 515.

Workup
