Participants

Reaction Steps

Tetra-n-butylammoniumfluoride (1 mol/l tetrahydrofuran solution) 2.2 ml was added to compound (45) 496 mg in tetrahydrofuran 10 ml with cooling in ice. The mixture was stirred for 3 h, diluted with water and ethyl acetate and, extracted with ethyl acetate. The extracts were washed with brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue obtained was chromatographed on aluminum oxide in ethyl acetate:hexane (2:1) to give colorless crystals, 273.2 mg. This was recrystallized from acetone-isopropyl ether to give the titled compound as colorless crystals, m.p.175-176° C., 2654 mg. Yield 88%.
