Procedure

To the resultant compound from Example 6 (2.51 g, 8.84 mmol) in methylene chloride (20 ml) was added diisopropylethylamine (4.60 ml, 26.4 mmol) and methoxyethoxychloromethane (3.00 ml, 26.3 mmol). After stirring at room temperature for 24 h the mixture was concentrated, diluted with ethyl acetate, washed with 0.5M H3PO4, saturated NaHCO3 solution, then brine, dried over Na2SO4, and evaporated. Chromatography on silica gel with ethyl acetate/ hexane mixtures afforded 2.63 g (80%) of the desired product as an oil. EI-MS: M+ =371.
