Participants

Reaction Steps

3-[6-(2-Aminoethoxy)-4-oxoquinazolin-3(4H)-yl]-N-cyclopropyl-4-methylbenzamide (0.1 g), acetyl chloride (0.025 ml), and triethylamine (0.074 ml) were stirred in methylene chloride (2 ml) under an atmosphere of argon for 2 hours at room temperature. The reaction mixture was diluted with ethyl acetate and washed with water (2×), brine, dried (magnesium sulfate) and concentrated. Purification by column chromatography on a silica column eluting with 10% methanol/ethyl acetate gave the title compound (0.067 g) as a white solid; NMR Spectrum: (DMSOd6) 0.56 (m, 2H), 0.69 (m, 2H), 1.82 (s, 3H), 2.14 (s, 3H), 2.86 (m, 1H), 3.47 (m, 2H), 4.13 (m, 2H), 7.52 (m, 2H), 7.59 (s, 1H), 7.74 (d, 1H), 7.83 (s, 1H), 7.90 (d, 1H), 8.09 (t, 1H), 8.20 (s, 1H), 8.43 (d, 1); Mass Spectrum: M+H+ 421.
