• Several N-(2-arylethyl)-substituted thioamides (IVa〜IVf) were synthesized from the dithioesters (V or VI) and the 2-arylethylamines in good yield, in order to test direct cyclization of the thioamides to the corresponding 3,4-dihydroisoquinolines by a Bischler-Napieralski type reaction The comparative study of the infrared absorption spectra of the thioamides with those of the corresponding acid amides shows that the most characteristic absorption bands of the C=S group in the thioamides (IVa〜IVf) fall within four regions, namely, 1508〜1520,1388〜1416,1330〜1352,and 1100〜1150cm^<-1>.
