Procedure

Compound A1 (1.22 g, 4.28 mmol) obtained in Reference Example 1 was dissolved in dichloromethane (12.0 mL). Diisopropylethylamine (1.5 mL, 8.6 mmol) and 2-(trimethylsilyl)ethoxymethyl chloride (1.10 mL, 6.40 mmol) were added and the mixture was stirred at room temperature for minutes. Water was added to the reaction mixture. Extraction with ethyl acetate, washing with saturated brine and drying over anhydrous sodium sulfate were performed. After filtration, the solvent in the filtrate was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=5/1) to give Compound A5 (1.68 g, 94% yield).
