Versuchsvorschrift
To a suspension of {[4-[(3,4-dichlorophenyl)amino]-6-(methyloxy)quinazolin-7-yl]oxy}acetonitrile (14.7 g; 39.3 mmol) in EtOH (600 ml) was added a 50% aqueous solution of NH2OH (24.1 ml; 393 mmol) and the reaction mixture was refluxed for 2 hours. The solvent was evaporated off and the residue was triturated with ether, collected by filtration and dried under vacuum to give 2-{[4-[(3,4-dichlorophenyl)amino]-6-(methyloxy)quinazolin-7-yl]oxy}-N-hydroxyethanimidamide (14.5 g; 90% yield). 1H NMR (400 MHz; DMSO-d6): 3.98 (s, 3H), 4.58 (s, 2H), 5.70 (s, 2H), 7.38 (s, 1H), 7.65 (d, 1H), 7.84 (s, 1H), 7.89 (dd, 1H), 8.26 (d, 1H), 8.55 (s, 1H), 9.41 (s, 1H), 9.64 (s, 1H); MS (EI) for C17H15Cl2N5O3: 408.05 (MH+).
