Reaction Steps

Twenty-four grams of trans N-(2-ETHYLAMINOCYCLOHEXYL)-p-TOLUENESULFONAMIDE from Example III,200 ml of methylenechloride, 24ml of triethylamine and 20 grams of ψ-acid chloride of o-benzoylbenzoic acid were mixed together and refluxed 4 hours. The mixture was extracted successively with water, 15% hydrochloric acid, and saturated sodium carbonate solution. The methylenechloride solution was dried over magnesium sulfate, then evaporated to dryness. The residue was slurried with ethyl acetate and filtered. Recrystallization from ethyl acetate afforded trans-2-BENZOYL-N-[2-(p-TOLUENESULFONAMIDO)CYCLOHEXYL]-N-ETHYL BENZAMIDE, mp. 201.5°-204°C.
