Procedure

To a solution of the compound of example 80 (1.75 g, 8.83 mmol) in dry CH2Cl2 (40 mL) was added benzyl alcohol (1.83 mL, 17.7 mmol), DMAP (108 mg, 0.88 mmol) and EDC (1.91 g, 10.0 mmol). The mixture was then stirred at room temperature for 18 h. The mixture was concentrated in vacuum, taken-up in ethyl acetate and washed with NaHCO3 (5%) and H2O. Drying (Na2SO4) and concentration gave 2.8 g of a pale yellow oil which was purified by flash chromatography (SiO2, ethyl acetate:hexane (1:1)) to give 1.92 g of the title compound.
