Procedure

The compound of Example 212 (1.12 g) was dissolved in acetonitrile (30 mL). To this solution, diisopropylamine (0.58 mL) and MOMCl (0.25 mL) were added while the solution was stirred and chilled in an ice bath. The mixture was stirred overnight. Subsequently, water was added and the mixture was extracted with ethyl acetate. The extract was washed with a saturated aqueous solution of sodium chloride and the organic phase was dried over anhydrous magnesium sulfate. The solvent was concentrated and the residue was purified on a silica gel column chromatography (hexane:ethyl acetate=5:1) to give the desired product as a colorless oil (1.12 g).
