Versuchsvorschrift

A solution of 4-tert-butyl-2-(2-oxo-2-phenylethyl)-cyclohexanone (0.219 gm) in glacial acetic acid (3.0 mL) in a 25-mL round-bottomed flask, under nitrogen, was fitted with a heating mantle and reflux condenser. To this solution was added 3-aminobenzoic acid (0.138 gm), which was then heated at 110 C for 3 hr. The solution was cooled to ambient temperature, 8 mL water was added, and the suspension was stirred 18 hr under nitrogen. The solid was filtered, washed with water, and recrystallized in acetonitrile to provide 0.123 gm of the pure product.
