Description générale
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.

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
