실험 절차

This titled amide was prepared by general procedure B from trans-2-(dimethylamino)cyclohexylamine and 3-trifluoromethylbenzoyl chloride. The crude oil was converted to the salt with 1 mole of p-toluenesulfonic acid in ether, and was crystallized from MeOH-ether, 47% yield, colorless plates, m.p. 208°-209°. uv λmax 222 nm (ε 22,150); sh 227 (17,900); sh 259 (1,550); sh 266 (1,100); sh 274 (566). ir NH/N+H 3280, 3040; C=O 1660; C=C/amide II 1615, 1595, 1550, 1495; CF3 /SO3- /CN 1335, 1320, 1275, 1200, 1180, 1160, 1120, 1075, 1035, 1010; aromatic/SO3- 705, 690, 680. NMR in CDCl3 (100 MHz) was in accord. Mass spectrum M+ 314.
