Procedure

2-Isothiocyanatopyridine (4 mmol), prepared from 2-aminopyridine employing general procedure A, was reacted with methyl 3,4-diaminobenzoate as described in general procedure B to afford 2-(pyridin-2-ylamino)-1H-benzimidazole-5-carboxylic acid methyl ester. This ester was hydrolyzed, following general procedure C, to obtain 2-(pyridin-2-ylamino)-1H-benzimidazole-5-carboxylic acid.
