Reaction Steps
A mixture of the compound of Example 18 (0.42 g), ethylene carbonate (0.088 g), tetraethylammonium iodide (0.026 g) and DMF (10 ml) was stirred at 100° C. for 2 hours. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography (eluent: 50%→90% ethyl acetate/hexane gradient), thereby giving 0.26 g of the desired compound. HPLC retention time: 6.31 minutes.
