Versuchsvorschrift
A mixture of 100 g of 3-chloro-4-fluoroaniline and 400 ml of 97% formic acid was refluxed (106° C.) for three hours. The mixture then was poured into ice water and the resulting mixture was filtered. The solid was washed with water and dried to give N-(3-chloro-4-fluorophenyl)formamide (J. Org. Chem., 26, 2563 (1961)) (1A), as a colorless crystalline solid, mp: 94°-97° C.
