実験手順

1-Methyl-5-(1,3-dioxolan-2-yl)-imidazole (0.09 g) in dry THF (5 ml) under N2 was cooled to −78° C. and treated with n-butyl lithium (0.4 ml, 1.6M). After 30 minutes, tributyl tin chloride (0.17 ml) was added, the mixture allowed to warm to 20° C. and stirred for 1 hour. (4-Benzyloxy-phenyl)-(6-iodoquinazolin-4-yl)-amine (0.191 g), catalytic quantities of 1,4-bis-(diphenylphosphino)-butane palladium (II) chloride and silver (I) oxide (0.052 g) were added and the mixture heated at reflux for 18 hours. The mixture was absorbed onto silica and chromatographed to give the title compound (0.045 g); m/z (M+1)+ 480.
