5-{(1R)-2-[allyl(methyl)amino]-1-methylethoxy}-N-{3-methyl-4-[(6-methylpyridin-3-yl)oxy]phenyl}quinazolin-4-amine → 5-[(1R)-1-methyl-2-(methylamino)ethoxy]-N-{3-methyl-4-[(6-methylpyridin-3-yl)oxy]phenyl}quinazolin-4-amine

Participants

Reaction Steps

A mixture of 5-{(1R)-2-[allyl(methyl)amino]-1-methylethoxy}-N-{3-methyl-4-[(6-methylpyridin-3-yl)oxy]phenyl}quinazolin-4-amine (2.25 g, 4.8 mmol) and chlorotris(triphenylphosphine)rhodium(I) (463 mg, 0.48 ml) in acetonitrile—water (17 ml:3 ml) was heated at reflux for 3 hours. After cooling, the solvents were evaporated under vacuum. The residue was purified by chromatography on silica gel (eluant: 2 to 4% methanol in DCM) to give 5-[(1R)-1-methyl-2-(methylamino)ethoxy]-N-{3-methyl-4-[(6-methylpyridin-3-yl)oxy]phenyl}quinazolin-4-amine (1.70 g, 83%); Mass spectrum: MH+ 430.
