実験手順

To a solution of 950 mg of 10c in 5 ml of THF was added 5 ml of 1M tetra-n-butyl ammonium fluoride in THF. The mixture was stirred for 1 hr at RT and then poured into 50 ml of water and extracted with ethyl acetate. The crude product thus obtained was chromatographed on silica gel (using a gradient of heptane/ethyl acetateas eluent) and provided 700 mg of 10d, as a colorless oil; Rf 0.35 (heptane/ethyl acetate 1/1);
