In an analogous manner to Example 10, 5-(4-(4-Benzyloxy-phenylamino)-quinazolin-6-yl)-furan-2-carbaldehyde hydrochloride (0.200 g, 0.436 mmol) was reacted with 2-(methanesulphonamido)ethylamine (0.350 g, 2.53 mmol). On completion of the reaction the mixture was acidified with dilute HCl and diluted with water, but no solid was formed. The mixture was concentrated in vacuo, and the residue was washed with acetone, 2N HCl and acetone again, and dried at 60° C. in vacuo to give the title compound as a yellow solid (0.210 g, 0.340 mmol, 78%); δH [2H6]DMSO 12.01 (1H,s), 9.82 (1H, br s), 9.77 (1H,s), 8.88 (1H,s), 8.40 (1H,d), 8.02 (1H,d), 7.76 (2H,d), 7.31-7.53 (6H,m), 7.14 (2H,d), 6.84 (1H,d), 5.18 (2H,s), 4.40 (2H,s), 3.34-3.48 (2H, m), 3.08-3.18 (2H,m), 2.96 (3H,s); m/z (M+1+) 544.
