PROCEDURE
实验过程
With stirring at 0° C., a solution of 115 mg of potassium monopersulfate triple salt in 0.5 ml of water is added dropwise to a solution of 74 mg of N-tert-butoxycarbonyl-2(R,S)-methyl-4(S)-hydroxy-5(S)-amino-7(S)-isopropyl-8-[3-(methylthio-methoxy)-4-tert-butyl-phenyl]-octanoic acid (N-butyl)amide in 0.5 ml of methanol and the mixture is then stirred at room temperature for a further 20 hours. The reaction mixture is partitioned between dichloromethane and water. The organic phases are concentrated by evaporation and the title compound is obtained from the residue by FC (11 g of silica gel, ethyl acetate/hexane=1:1): Rf (ethyl acetate/hexane=1:1)=0.26; FAB-MS (M+H)+ =627.
