Reaction Steps

(4-Benzyloxy-phenyl)-(6-iodoquinazolin-4-yl)-amine (1.2 g) in dioxane (10 ml) under N2 was treated with tributyltin cyanide (0.79 g) and catalytic quantities of 1,4-bis-(diphenylphosphino)-butane palladium (II) chloride and tetrakis (triphenylphosphine) palladium at reflux for 23 hours. The mixture was absorbed onto silica and chromatographed to give the title compound (0.65 g); δH [2H6]DMSO 10.01(1H,s), 9.14(1H,s), 8.63(1H,s), 8.15(1H,d), 7.87(1H,d), 7.73(2H,d), 7.45(5H,m), 7.10(2H,d), 5.13(2H,s); m/z (M+1)+353.
