Versuchsvorschrift
Prepared according to Procedure B from (1-benzyl-1H-indazol-5-yl)-(6-bromoquinazolin-4-yl)-amine (4.3 g), 2-(tributylstannyl)-5-(1,3-dioxolan-2-yl)-furan (J. Chem. Soc., Chem Commun., (1988), 560) (10 g) and 1,4-bis(diphenylphosphino) palladium (II) chloride (1 g) in dioxane. The solvent was removed in vacuo and the residue chromatographed on silica. Subsequent trituration gave the title compound δ H [2H6]-DMSO 10.13 (1H, s), 8.85 (1H, s), 8.54 (1H, s), 8.20 (3H, m), 7.80 (3H, m), 7.30 (5H, m), 7.13 (1H, d), 6.79 (1H, d), 6.04 (1H, s), 5.71 (2H, s), 4.15 (4H, m).
