General description

The carbonyl-scavenging ability of 2-amino-1-methylbenzimidazole has been investigated. Mechanism of Menshutkin reaction between 2-amino-1-methylbenzimidazole and iodomethane has been studied in gas phase and in liquid acetonitrile. It is reported to form adducts with natural allyl, phenethyl, and benzyl isothiocyanates.

Application

2-Amino-1-methylbenzimidazole may be used for the preparation of 2- or 3-carboxy-4H-pyrimido[2,1-b]-benzazol-4-ones and novel functionalized spiropyran′s derivatives of 2H-1,3-benzoxazinone series.

The quaternization reaction between 2-amino-1-methylbenzimidazole and iodomethane was investigated in the gas phase and in liquid acetonitrile. Both experimental and theoretical techniques were used in this study. In the experimental part of this work, accurate second-order rate constants were obtained

Reactions of 2-aminobenzothiazole, 2-aminobenzoxazole, and 2-amino-1-methylbenzimidazole with dimethyl aminofumarate (DMAF) or diethyl ethoxymethylenemalonate (DEEM) led to 2- or 3-carboxy-4H-pyrimido[2,1-b]-benzazol-4-ones, respectively. Subsequent derivatization of these carboxylic acids gave the corresponding tetrazolylcarboxamides and tetrazoles. These acidic compounds were tested in the rat
