Procedure

The compound (100 mg) of Example 16 was dissolved in N,N-dimethylacetamide (2 ml), followed by the addition of 2-ethylbutanoyloxymethyl iodide (50 mg). They were reacted for 1 hour. Ethyl acetate (50 ml) was added. The resulting mixture was washed with water, dried over magnesium sulfate, and then concentrated under reduced pressure. Ether was added to the residue and the resulting solid was collected by filtration, whereby the title compound (55 mg) was obtained.
