Procedure

To a solution of the product of Example 407 (700 mg) in THF (20 ml) was added thiocarbonyldiimidazole (280 mg) and the mixture was stirred at room temperature for 30 minutes. Water and ethyl acetate were added to the reaction mixture. The organic layer was extracted, and the solvent was distilled off under reduced pressure. To the residue were added THF (50 ml) and boron trifluoride diethyl etherate (0.8 ml), and the mixture was stirred at room temperature for 1 hour. Chloroform, 2-propanol and water were added to the reaction mixture. The organic layer was extracted, and the solvent was distilled off under reduced pressure. The residue was reslurried with acetone to the titled compound (180 mg). MS m/z: 577(M+1)
