Versuchsvorschrift
4-(4-Oxocyclohexyl)benzoyl chloride [obtainable by reacting 0.75 mol (130.7 g) of 4-phenylcyclohexanone with 1 mol of oxalyl chloride and 2 mol of AlCl3 in dichloromethane, followed by hydrolysis with ice-water/HCl] is added to an aqueous solution (15%) of 3 mol of dimethylamine and the mixture is stirred for 2 hours at 0 to 5°. It is worked up in conventional manner to give 125.2 g of N,N-dimethyl-4-(4-oxocyclohexyl)benzamide, m.p. 118°; yield: 68% based on 4-phenylcyclohexanone.
