Reaction Steps

1-Cyclohexyl-2-furan-3-yl-1H-benzoimidazole-5-carboxylic acid hydrazide (0.022 g, 0.068 mmol) and methyl-4-chlorocarbonylbenzoate (0.013 g, 0.068 mmol) were stirred in DMF (1 mL) in the presence of DIEA (0.018 g, 0.14 mmol) for 2 h. An aqueous solution of NaOH (2.5 N, 0.22 mL, 0.55 mmol) was then added and the mixture was stirred for 2 h at room temperature. The reaction mixture was acidified by the addition of AcOH and purified by reversed phase C18 preparative HPLC to give the title compound of example 143.
