Procedure

Acetyl chloride (24 μl, 0.33 mmol) was added drop wise to a solution of 5-[(1R)-1-methyl-2-(methylamino)ethoxy]-N-{3-methyl-4-[(6-methylpyridin-3-yl)oxy]phenyl}quinazolin-4-amine (129 mg, 0.30 mmol, obtained as described in Example 103, preparation of starting materials) and DIPEA (105 μl, 0.6 mmol) in DCM (5 ml). The mixture was stirred at room temperature for 2 hours and diluted with DCM. The solution was washed with water and brine, and dried over MgSO4. After evaporation of the solvents, the residue was purified by chromatography on silica gel (eluant: 2 to 4% methanol in DCM) to give the title compound (84 mg, 60%) as a pale solid; NMR spectrum (CDCl3) 1.55 (d, 3H), 2.08 (s, 3H), 2.30 (s, 3H), 2.53 (s, 3H), 3.08 (s, 3H), 3.56 (dd, 1H), 3.93 (dd, 1H), 5.09 (m, 1H), 6.92 (d, 1H), 7.12 (m, 3H), 7.50 (m, 2H), 7.65 (m, 1H), 7.70 (s, 1H), 8.27 (s, 1H), 8.62 (s, 1H); Mass spectrum: MH+ 472.
