実験手順

The titled amide was prepared according to general procedure B using p-cyanobenzoyl chloride (1.65 g.; 0.01 mole), the trans-2-(dimethylamino)cyclohexylamine (1.42 g.; 0.01 mole) and triethylamine (1.01 g.; 0.01 mole) but using CH2Cl2 for extraction. The crude solid was crystallized from ether to give colorless needles, 1.71 g. (63% yield), m.p. 160°-161°. uv λmax 236 nm (ε 17,900); sh 285 (2,550). ir NH 3320; N-alkyl 2780; C=N 2220; C=O 1635; C=C 1610, 1500; amide II 1550; aromatic 860. NMR in CDCl3 (60 MHz) was in accord. Mass spectrum M+ 271.
