Procedure
The product from example 55 step (v) (3.24 g) was added to a preformed solution of methanol (200 ml) and acetyl chloride (20 ml) and stirred at RT overnight. The mixture was evaporated under reduced pressure to give an oil. The oil was purified by flash column chromatography (eluent 1:1 ether/isohexane) to give the subtitle compound (3.16 g).
