Participants

Reaction Steps

To a solution of 2-[(trans-4-hydroxycyclohexyl)amino]-7-methylquinazolin-8-ol (20 g, 0.073 mol) in DMF (160 mL) was added K2CO3 (10.6 g, 0.077 mol) in one portion at room temperature. Then a solution of bromoacetic acid methyl ester (11.5 g, 0.075 mol) in DMF (40 mL) was added dropwise. After the addition, the reaction mixture was stirred at room temperature overnight. The mixture was diluted with water (400 mL) and extracted with EtOAc (200 mL×3). The combined organic layers were washed with water (150 mL), dried over anhydrous Na2SO4 and evaporated in vacuo to give the crude product. The crude product was re-crystallized from EtOH (150 mL) to give the title compound (13 g, 51.4%) as an off-white solid.
