Procedure

To a solution of 2-[(2-chloro-6-methylphenyl)amino]-N-[2-fluoro-5-(trifluoromethyl)phenyl]-7,7-dimethyl-7,8-dihydro-1H-furo[3,2-e]benzimidazole-5-carboxamide (Example-110, 0.100 g) in acetone was added oxalic acid. The reaction mass was refluxed for 3 h. The reaction mass was filtered and obtained residue was washed with DEE to afford 0.100 g desired product.
