Mode opératoire

Compound 38 was prepared by the basic process from 5.0 mmol 3,5-dichloroaniline, 5.5 mmol ethylglyoxalate solution (50% toluene), 15.0 mmol 3-bromostyrene and 5.0 mmol trifluoroacetic acid in 30.0 ml acetonitrile. Subsequent saponification was carried out using 1.0 ml of sodium hydroxide solution (6N water) in 20.0 ml of ethanol.
