Reaction Steps

A solution of 1H-pyrrolo[3,2-b]pyridine (33.0 mg, 0.279 mmol) in 4 mL of DMF was treated with NaH (60% in mineral oil, 16.8 mg, 0.419 mmol) at room temperature. After 30 minutes, 5-chloro-7-[1,1-dimethyl-2-(2-trifluoromethyloxiranyl)ethyl]-2,3-dihydrobenzofuran (188 mg, 0.558 mmol) was added and the resulting mixture was stirred overnight. The reaction was then diluted with 5 mL of ethyl acetate and quenched with 5 mL of saturated ammonium chloride solution. The aqueous layer was extracted with 5 mL of ethyl acetate. The combined organic layers were dried over magnesium sulfate, filtered, and concentrated in vacuo. The residue was triturated with diethyl ether to afford 55.0 mg (45% yield) of the title product as white solid.
