Reaction Steps

A solution of the product of example 43 (19 mg, 0.082 mmol) in pyridine (0.40 ml) was treated with acetic anhydride (0.037 ml, 0.36 mmol) in two portions over 48 h. The reaction was subsequently concentrated to dryness and the residue coevaporated with AcOH under reduced pressure. The crude product was purified as described in example 46. The pure fractions with product were combined and lyophilized to provide 9 mg of the title compound.
