7.8 g (24.4 mmol, 1.5 eq) of mercury acetate are added to a solution of 4 g (16.3 mmol, 1 eq) of (1) dissolved in 100 ml of acetic acid. The reaction mixture is stirred for 1 day at ambient temperature, and then an additional 1 g (3.13 mmol, 0.2 eq) of mercury acetate is added. After stirring for a further 1 day at ambient temperature, the reaction is complete. The acetic acid is evaporated off under high vacuum and the residue is taken up in ether. The organic phase is extracted with a saline solution and then dried over Na2SO4, filtered and evaporated under reduced vacuum, to give a yellow oil. The crude product is chromatographed on silica gel, to give a colorless oil (4.4 g).
