Versuchsvorschrift
a mixture of 360 mg of 3-aminobenzaldehyde (0.3 mmoles) and 460 mg of 4-chloro-phenylisocyanate (0.3 mmoles) in 3 ml of DMF is heated under microwave irradiation at 110° C. for 10 minutes. The precipitate formed is filtered giving the desired 1-(4-Chloro-phenyl)-3-(3-formyl-phenyl)-urea. Analytical LC/MS method A: ([M+H]+): 351, RT: 5.30 min (gradient 5 to 85% acetonitrile in 7 min).
