Reaction Steps

To a solution of 6-(2-(4-methoxybenzyloxy)-4-methylpyridin-3-yl)quinazolin-2-amine (0.650 g, 1.75 mmol) in CH2Cl2 (1 mL) at RT was added TFA (1.00 ml, 13.0 mmol). After 10 min the solvent and excess acid was removed in vacuo. The residue was taken up in EtOAc and saturated NaHCO3 was added. The resulting white precipitate was removed by filtration. The solid material, 3-(2-aminoquinazolin-6-yl)-4-methylpyridin-2(1H)-one, was dried in vacuo and used without further purification. M+H+=253.1.
