HCID 128066625-Butyryl-6-methoxy-1-methyl-benzimidazole-2-carboxylic acid

Procedure

In a manner analogous to that described in Example 12, 5.2 g of 5-butyryl-6-methoxy-1-methyl-benzimidazole-2-methanol are oxidised with 4.5 g of potassium permanganate to give 5-butyryl-6-methoxy-1-methyl-benzimidazole-2-carboxylic acid with a melting point above 85° (decomposition)
