実験手順
to a solution of 242 mg of 3-aminobenzaldehyde (2 mmoles) and 250 μl of 4-chlorobenzoyl chloride (2 mmoles) in 5 ml of DMF is added 700 μl of DIEA (4 mmoles). The reaction is irradiated in under microwaves at 110° C. for 10 minutes. The precipitate formed is filtrated and washed with methanol. 670 mg of 4-Chloro-N-(3-formyl-phenyl)-benzamide are isolated as a white solid (yield=85%). Analytical LC/MS method A: ([M+H]+): 260
