Procedure

4,5-Dibromomethyl-2-oxo-1,3-dioxolene (188 mg, 0.69 mmol) was dissolved in acetonitrile (5.0 mL). Thereto were added 2-(N-Boc-amino)isobutyric acid (70 mg, 0.35 mmol) and potassium carbonate (48 mg, 0.35 mmol). This mixture was stirred at 25° C. for 18 hours. After the ordinary post-treatment, the reaction product was purified by thin-layer chromatography (developed with chloroform) to obtain Compound S-33 (50 mg, yield 18%).
