Reaction Steps

A solution was prepared by dissolving 10 mg (0.019 mmol) of (3S,5R,6S,7S)-7-(benzyloxymethyl)-6-(4-fluorophenyl)-3-hydroxy-3-(2-methoxy-5-(trifluoromethyl)phenyl)-1-oxaspiro[4.4]nonane in 0.20 mL of trifluoroacetic acid at RT, and triethylsilane (0.009 mL, 7 mg, 0.06 mmol) was added immediately. After 30 min., the reaction was diluted with 25 mL of ethyl acetate and washed with 5 m L of saturated aqueous sodium bicarbonate and 5 mL of saturated aqueous sodium chloride. The organic solution was dried over sodium sulfate, decanted, and evaporated. The crude product was purified by preparative TLC, eluting with 3% ethyl ether in toluene, to yield 2.4 mg of the title compound.
