Sodium hydride → 7-Isopropyl-9-methoxy-2-(quinolin-2-ylmethyl)-3,4-dihydro-2H-pyrazino[1,2-c]pyrimidine-1,6,8(7H)-trione

Participants

Reaction Steps

To a cold solution (0° C.) of 7-isopropyl-9-methoxy-3,4-dihydro-2H-pyrazino[1,2-c]pyrimidine-1,6,8(7H)-trione (0.050 g, 0.197 mmol) in DMF (1.5 mL) was added 2-(chloromethyl)quinoline hydrochloride (0.051 g, 0.237 mmol). Sodium hydride (60% suspension in mineral oil, 0.022 g, 0.868 mmol) was added. The mixture was warmed to room temperature and stirred for 24 hours. The reaction mixture was partitioned between water and EtOAc. The organic phase was washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was used in the next step without purification. HPLC RT=3.47 min (Method A); ES MS (M+H)=395.3.
