Procedure
A solution of KOH (1.73 g, 31 mmol) in water (50 mL) was added to a solution of compound 55 (10 g, 31 mmol) in ethyl acetate (100 mL). The aqueous layer stained in yellow. The mixture was stirred at room temperature for 1 h (TLC monitoring, eluent: CH2Cl2-ethyl acetate, 1:1). If necessary, additional portions of KOH solution (0.5 eq.) were added. The organic layer was separated, washed thoroughly with water, a solution of citric acid (to pH 7), again with water, dried over Na2SO4, and evaporated. Yield of 56: 6.6 g (93%) as a yellowish fluid oil.
