Reaction Conditions

Reaction Steps

Palladium acetate (0.02 g) and triphenylphosphine (0.038 g) was added to a stirred mixture N-cyclopropyl-3-(6-iodo-4-oxoquinazolin-3(4H)-yl)-4-methylbenzamide (0.20 g), methyl acrylate (0.4 ml) and triethylamine (0.63 ml) in anhydrous tetrahydrofuran (15 ml) under an argon atmosphere. The mixture was heated to 60° C. and stirred for 2 hours. The reaction mixture was evaporated, dissolved in ethyl acetate (100 ml) and washed with water (100 ml) and brine (100 ml). The organic phase was dried (magnesium sulphate) and evaporated and the residue purified by column chromatography on a silica column using initially iso-hexane and then a 1:1 mixture of iso-hexane and ethyl acetate as eluent. There was thus obtained the title compound (0.14 g); NMR Spectrum: (DMSOd6) 0.57 (m, 2H), 0.70 (m, 2H), 2.17 (s, 3H), 2.86 (m, 1H), 3.76 (s, 3H), 6.80 (d, 1H), 7.55 (m, 2H), 7.63 (m, 1H), 7.86 (m, 2H), 8.31 (m, 1H), 8.37 (s, 1H), 8.45 (m, 2H); Mass Spectrum: M+H+ 404.
