Mode opératoire

The compound ([3]-(34)-587) (0.07 g) prepared in Example 38 and 4-dimethylaminopyridine (0.01 g) were dissolved in dry pyridine (1 ml). Valeryl chloride (0.043 g) was added dropwise by a syringe while cooling on ice. The mixture was stirred at room temperature for 2 hours, then, poured into water (20 ml), extracted with chloroform (10 ml) twice, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to obtain the compound ([3]-(35)-587') (0.08 g) as a light yellow solid.
