Procedure

A solution of methoxyacetic acid (0.019 mL, 0.24 mmol) in THF (5.0 mL) was added with Compound 95 (0.10 g, 0.29 mmol), 1-hydroxybenzotriazole monohydrate (52 mg, 0.337 mmol) and 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (69 mg, 0.36 mmol), followed by stirring at 60° C. for 1 hour. The reaction mixture was added with ethyl acetate and saturated aqueous sodium hydrogencarbonate solution (4.0 mL) and was extracted. The organic layer was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/methanol=10/1), and the product was added with ethyl acetate, then precipitate was collected by filtration to obtain Compound 100 (39 mg, 39%).
