Participants

Reaction Steps

A solution of 4-[2-[(4-chloro-2-methoxy-6-methylphenyl)amino]-1-(2-hydroxyethyl)-1H-benzimidazol-7-yl]heptan-4-ol (100 mg, 0.22 mmol) in pyridine (5 mL) was treated with acetic anhydride (1 mL) and stirred at room temperature overnight. The reaction mixture was concentrated to dryness, diluted with aqueous sodium hydrogen carbonate, and extracted with ethyl acetate. The organics were dried over magnesium sulfate, filtered, and concentrated in vacuo. The residue was chromatographed on a silica gel to give 97 mg (0.20 mmol, 89%) of the title compound.
