Reaction Steps

Sodium hydride (960 mg, 60% dispersion in oil, 20 mmol) was added portion wise to an ice-cooled solution of (2R)-1-[allyl(methyl)amino]propan-2-ol (3.87 g, 30 mmol, obtained as described in Example 2.3, preparation of starting materials) and 5-fluoro-N-{3-methyl-4-[(6-methylpyridin-3-yl)oxy]phenyl}quinazolin-4-amine (3.6 g, 10 mmol) in THF (25 ml). The mixture was heated at 65° C. for 24 hours. After cooling, the solvents were evaporated under vacuum. The mixture was diluted with DCM, and washed with water and brine. The organic layer was 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 5-{(1R)-2-[allyl(methyl)amino]-1-methylethoxy}-N-{3-methyl-4-[(6-methylpyridin-3-yl)oxy]phenyl}quinazolin-4-amine (2.4 g, 51%) as a brown oil; Mass spectrum: MH+ 470.
