摘要:
An object is to provide a thiazole derivative produced from easily available raw materials by a simplified production process. Provided are a process for producing a novel thiazole derivative represented by the general formula (I), which is characterized by adding a strong base to a thioamide represented by the general formula (II) and reacting the mixture with a thioformamide represented by the general formula (III), and a novel thiazole derivative.
摘要:
The compounds are N-(heterocyclomethylthioalkyl) derivatives of alkylguanidines, C-alkyl and C-aryl amidines and S-alkylisothioureas. The compounds may also have N'-lower alkyl or N'(heterocyclomethylthioalkyl) substituents. Three compounds of the invention are S-methyl-N-[2-(5-methyl-4-imidazolylmethylthio)ethyl]isothiourea, N,N'-bis-[2-(5-methyl-4-imidazolylmethylthio)ethyl]acetamidine, N,N'-bis-[2-(5-methyl-4-imidazolylmethylthio)ethyl]N"-methylguanidine. The compounds of this invention are histamine H.sub.2 -antagonists.
摘要:
The present 2-substituted imidazolines and 2-substituted-3,4,5,6-tetrahydropyrimidines possess valuable anti-depressant and anti-inflammatory properties. The compounds are prepared by the condensation of an appropriately substituted nitrile with a diamine. For example, condensation of 2-pyridylbenzyl cyanide with 1,2-ethylene diamine or with 1,3-propylene diamine produces a 2-(2-pyridylbenzyl) imidazoline or a 2-(2-pyridylbenzyl)-3,4,5,6-tetrahydropyrimidine.
