Participants

Reaction Steps

To a solution of 6-(5-methyl-1,3,4-oxadiazol-2-yl)-1-(4-piperidinyl)-1H-benzimidazole (0.25 g, 0.88 mmol) and triethylamine (0.24 mL, 1.76 mmol) in tetrahydrofuran (5 mL) was added methanesulfonyl chloride (0.10 mL, 1.32 mmol) at 0° C., and the resulting mixture was stirred at room temperature for 1 hr. The reaction solution was filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by basic silica gel column chromatography (ethyl acetate/methanol=1/0-19/1) and recrystallized from diethyl ether/methanol to give the title compound (0.19 g, yield 60%) as colorless crystals.
