Procedure

The product from step (iv) (0.564 g) was dissolved in 50% aqueous acetone (10 ml), sodium bicarbonate (0.94 g) added, followed by a solution of oxone (1.5 g) in water (ml) and stirred for 3 h. The reaction was quenched with aqueous sodium metabisulfite, extracted with EtOAc, washed with aqueous potassium carbonate, dried (Na2SO4) and evaporated to give the subtitle compound. Yield 0.32 g.
