Versuchsvorschrift
A mixture of 5.3 grams of methyl-2-hydroxy-5-(4'-fluorophenyl)-benzoate and 20 ml. of liquid ammonia is reacted in a bomb at 100° C. for 4 hours. After cooling the bomb is opened and the ammonia allowed to evaporate. The residue is then recrystallized from benzene to yield 2-hydroxy-5-(4'-fluorophenyl)-benzamide (m.p. 206° - 207° C.).
