Versuchsvorschrift

A mixture of 11.5 g. (0.05 mole) of 2-(p-hydroxyphenacyl)cyclohexanone, 7.6 g. (0.05 mole) of 5-aminosalicylic acid, and 40 ml. of glacial acetic acid was heated under reflux under nitrogen for 1.5 hours, cooled and filtered to provide 10.6 g. (61%) of solid, m.p. 214°-217°. Recrystallization from acetonitrile gave crystals, m.p. 217°-219°.
