Reaktionsschritte

In an analogous manner to Example 10, 5-(4-(4-Benzyloxy-phenylamino)-quinazolin-6-yl)-furan-2-carbaldehyde hydrochloride (0.217 g, 0.474 mmol) was reacted with N-methyl-N-(2-methanesulphonyl-ethyl)amine (0.41 1g, 3.0 mmol). Purification by silica gel chromatography, eluting with 2-3% MeOH/CHCl3, followed by trituration with ether, gave the title compound as a pale yellow solid (0.100 g, 0.184 mmol, 39%); δH [2H6]DMSO 9.84 (1H,s), 8.63 (1H,s), 8.48 (1H,s), 8.12 (1H,d), 7.78 (1H,d), 7.68 (2H,d), 7.13-7.52 (5H,m), 7.02-7.10 (3H,m), 6.55 (1H,d), 5.14 (2H,s), 3.70 (2H,s), 3.35-3.44 (2H, obscured by water), 3.05 (3H,s), 2.84 (2H,t), 2.28 (3H,s).
