Procedure

A solution of Example 33 (105 mg, 68% purity, 144 μmol) in THF/dichloromethane (1:2.5, 3.9 ml) was treated with sodium carbonate (179 mg, 1.6 mmol) and stirred at rt for 30 min. Acetyl chloride (30 μl, 424 μmol) was added, and the resulting mixture was stirred at rt for 30 min, then quenched with methanol (2 ml) and evaporated. Purification by preparative RP-HPLC (Reprosil C18, gradient 10-95% acetonitrile/0.1% aq. formic acid) afforded 30 mg (85% purity, 34% of th.) of the title compound.
