Procedure

To a solution of the compound obtained from step g above (0.22 g) in a solvent mixture of acetonitrile:water (3 mL:1 mL) at 0° C., sodium dihydrogenphosphate (0.021 g), sodium chlorite (0.081 g) and hydrogen peroxide (1 mL, 30% in water) were added. The reaction mixture was stirred for 2 hours at room temperature. The solvents were evaporated under reduced pressure to obtain a residue. Ethyl acetate and water were added to the resulting residue. The organic layer was separated, washed with water and brine, and dried over anhydrous sodium sulphate. The solvent was evaporated under reduced pressure to afford the title compound (0.2 g).
