Reaction Steps

N-Cyclopropyl-3-[6-[3-(dimethylamino)prop-1-yn-1-yl]-4-oxoquinazolin-3(4H)-yl]-4-methylbenzamide (0.097 g) and 10% Palladium on carbon (0.01 g) were stirred in ethanol (2 ml) and methanol (0.5 ml) under an atmosphere of hydrogen for 2 hours. The catalyst was removed by filtration through diatomaceous earth (Celite®) and the filtrate was concentrated under reduced pressure. The residue was purified by column chromatography on a silica column eluting with 10% methanol/ethyl acetate followed by 10% methanol/ethyl acetate+1% aqueous ammonia solution to give the title compound (0.068 g) as a white foam solid; NMR Spectrum: (DMSOd6) 0.56 (m, 2H), 0.70 (m, 2H), 1.78 (m, 2H), 2.15 (s, 9H), 2.23 (t, 2H), 2.78 (t, 2H), 2.86 (m, 1H), 7.53 (d, 1H), 7.71 (d, 1H), 7.78 (d, 1H), 7.83 (s, 1H), 7.91 (d, 1H), 8.02 (s, 1H), 8.25 (s, 1H), 8.42 (d, 1H); Mass Spectrum: M+H+ 405.
