Procedure

To a solution of the product of Example 407 (700 mg) in THF (20 ml) were added pyridine (0.21 ml) and thionyl chloride (0.1 ml) at 0° C., and the mixture was stirred at 0° C. for 1 hour and the mixture was stirred at room temperature for 30 minutes. Water, chloroform and 2-propanol were added to the reaction mixture. The organic layer was extracted and the solvent was distilled off under reduced pressure. The residue was purified by silica gel chromatography eluting with chloroform-methanol (5:1) to give the titled compound (170 mg). MS m/z: 581(M+1)
