Procedure
2.5 g (7.2 mmol) of 2,3-diamino-5-benzyloxy-benzoic acid benzyl ester was subjected to a similar cyclization condition as illustrated in intermediate A by using 2.3 g (21.6 mmol) of BrCN in methanol to produce 2-amino-6-benzyloxy-1H-benzoimidazole-4-carboxylic acid benzyl ester. LCMS: 375 (M+1)+.
