  摘要：

  New 2-[2-(phenylamino)thiazol-4-yl]ethanamine and 2-(2-benzhydrylthiazol-4-yl)ethanamine derivatives were prepared and tested in vitro as H-1 receptor antagonists. The compounds with 2-phenylamino substitution with meta-halide substituents at the phenyl ring, showed weak H-1-antagonistic activity (pA(2): 4.62-5.04) and this activity was completely lost in the case of meta-methyl substituent (pA(2) < 4). When the phenylamino group was replaced by benzhydryl groups of classic antihistamines, the resulting compounds exhibited slightly improved H-1-antagonistic activity (at the meta-position pA(2): 6.38-6.15; at the para-position pA(2): 6.04-5.87).

  Aromatic nitro compounds can be reduced with sulfurated sodium borohydride to the corresponding amine in high yields (≈80%) without affecting ester, nitrile, ether, halide or olefinic groups also present. With ortho-substituted nitro compounds the yields are around 60%.Primary aliphatic nitro compounds are reduced to the corresponding nitrile in high yields. Secondary aliphatic nitro compounds are

  into thiazoles (the expected Hantzsch reaction products). To the contrary, thiazoles are produced in the reactions of the same α-halo ketones with thioamides of phenylacetic, diphenylacetic, 3-indolylacetic, or cyanoacetic acids. The abnormal course of the Hantzsch reaction in the former case results from the fact that 4-hydroxy-Δ2-thiazolines, which are intermediates in the thiazole synthesis, undergo
