Procedimiento

The product of Step 1 is dissolved in 200 mL of 2:1 THF:water and to this solution is added 6 mL of acetic acid. The reaction mixture is heated at 45° C. for approximately 5 hours. The THF is removed under reduced pressure and the aqueous reaction mixture is adjusted to a pH in the range of 8 to 9 with 10% sodium carbonate and is then extracted with methylene chloride. The organic layer is dried over anhydrous sodium sulfate, filtered and concentrated in vacuo to afford the title compound.
