실험 절차
161 mg of 3-amino-2,2-di(methyl)propionamide obtained in Reference Example 2 (1.39 mmol) and 44 mg of 2-hydroxypyridine (0.46 mmol) were added to a solution of 263 mg of {(S)-1-[(2S,4S)-4-isopropyl-5-oxotetrahydrofuran-2-yl]-2-[4-(2-methoxymethoxyphenyl)-2,2-dimethyl-5-oxopiperazin-1-yl]ethyl}carbamic acid benzyl ester obtained in the above reaction (0.46 mmol) in triethylamine (4.6 ml), and the mixture was stirred at 80° C. for two hours. The reaction mixture was cooled and then concentrated under reduced pressure and further stirred at 80° C. for 9 hours. The reaction mixture was cooled and then water was added, followed by extraction with methylene chloride. Then, the organic layer was dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent:methylene chloride/methanol=40/3) to obtain 166 mg of {(1S,2S,4S)-4-(2-carbamoyl-2-methylpropylcarbamoyl)-2-hydroxy-1-[4-(2-methoxymethoxyphenyl)-2,2-dimethyl-5-oxopiperazin-1-ylmethyl]-5-methylhexyl}carbamic acid benzyl ester (yield: 52%).
