실험 절차

No. 6801291, tert-butyl (E)-(2S,3S)-11-(2-heptyl-[1,3]dioxolan-2-yl)-2-hydroxy-3-((S)-4-isopropyl-5,5-diphenyl-2-thioxo-oxazolidine-3-carbonyl)-2-(2-methoxy-ethyl)-undec-4-enoate (62 mg, 0.0824 mmol) and (S)-2-amino-3-(4-butoxy-phenyl)-N-methyl-propionamide (23 mg, 0.0989 mmol) were dissolved in dichloromethane. The solvent was distilled off under reduced pressure. The resulting residue was reacted at 45° C. for 4 days. After confirming the consumption of the starting materials by LCMS, the reaction mixture was purified with SP1 to obtain No. 6801292, tert-butyl (E)-(2S,3S)-3-[(S)-2-(4-butoxy-phenyl)-1-methylcarbamoyl-ethylcarbamoyl]-11-(2-hept yl-[1,3]dioxolan-2-yl)-2-hydroxy-2-(2-methoxy-ethyl)-undec-4-enoate (33 mg, 54% yield, ESI (LC/MS positive mode) m/z 762 (M+H); Rt 3.02 min.). To the obtained No. 6801292 (40 mg, 0.0526 mmol) were added dichloromethane (3.0 mL) and trifluoroacetic acid (1.0 mL), and the mixture was stirred at room temperature. After confirming the consumption of the starting materials by LCMS, the solvent was distilled off under reduced pressure. The residue was purified by preparative HPLC. The purified fraction was freeze-dried to obtain the title compound (27 mg, 78% yield, white powder).
