Participants

Reaction Steps

Ethyl chloroformate (0.058 ml) was added to a suspension of 4-(3-amino-4-fluoroanilino)-6,7-dimethoxyquinazoline (159 mg) and triethylamine (0.14 ml) in dry methylene chloride (3.5 ml) and the resulting mixture was stirred at ambient temperature for 18 hours. Methylene chloride (100 ml) was added and the mixture was washed with water and brine, dried over magnesium sulphate, filtered and evaporated to dryness. The residue was purified by silica column chromatography, eluting with 2% methanol in methylene chloride to yield the title compound as a solid (38 mg, 19%); NMR: 1.23 (t, 3H), 3.91 (s, 3H), 3.94 (s, 3H), 4.12 (m, 2H), 7.16 (s, 1H), 7.21 (m, 1H), 7.57 (m, 1H), 7.83 (s, 1H), 8.0 (m, 1H), 8.42 (s, 1H), 9.28 (s, 1H), 9.49 (s, 1H); m/s: M+H+ 387.
