Procedure

1.2 g (5.5 mmol) of 2,3-diamino-4,6-difluoro-5-methoxy-benzoic acid was subjected to a similar cyclization condition as illustrated in intermediate A by using 1.7 g (16.5 mmol) of BrCN in methanol to produce 2-amino-5,7-difluoro-6-methoxy-1H-benzoimidazole-4-carboxylic acid. LCMS: 244 (M+1)+.
