Two thiazolylindoles and a benzimidazole: novel compounds on the designer drug market with potential cannabinoid receptor activity.

Abstract

In a seizure of German customauthorities two 3-([1,3]-thiazol-2-yl)indoles (N-(2-methoxyethyl),N-iso-propyl-2-(1-pentyl-1H-indol-3-yl)-4-thiazolemethanamine (1) and N,N-diethyl-2-(1-pentyl-1H-indol-3-yl)-4-thiazolemethanamine (2)) and one benzimidazole (1-(cyclohexylmethyl)-2-[(4-ethoxyphenyl)methyl]-N,N-diethyl-1H-benzimidazole-5-carboxamide (6)) were seized as pure compounds. The compounds have been detected in Germany for the first time, and no analytical data had been previously published. Mass spectrometric (MS), infrared (IR) spectroscopic, and nuclear magnetic resonance (NMR) spectroscopic data are presented and the way of the structure elucidation of these rather uncommon compounds is discussed.
