Procedure

2-[4-(5-Chloro-2,3-dihydrobenzofuran-7-yl)-2-hydroxy-4-methyl-2-trifluoromethylpentyl]-1H-pyrrolo[3,2-b]pyridine-5-carbonitrile (100 mg, 0.22 mmol) was dissolved in 3 mL of THF and borane-methyl sulfide (10 M, 0.065 mL, 0.648 mmol) was added. The reaction was heated at reflux for 1 hour and then cooled to room temperature. 1 mL of a 6 N HCl solution was then added. The reaction was heated at reflux overnight. The reaction was cooled to room temperature, diluted with 50 mL of ethyl acetate, and then quenched with saturated sodium carbonate solution until the pH was 12. The organic layer was separated and aqueous layer was extracted with three 50 mL portions of ethyl acetate. The combined organic fractions were dried over sodium sulfate and the solvent was removed in vacuo. The residue was purified by preparative HPLC (polar condition) to give the title compound (49 mg, 49% yield).
