PROCEDURE

实验过程

A suspension of 41.37 g of methyl (1 S,2R)-[1 -benzyl-3-[(3 S,4aS,8aS)-3-tert-butoxycarbamoyl-octahydro-isoquinolin-2-yl]-2-hydroxy-propyl]-carbamate and 23.0 g of sodium hydroxide in 90 ml of ethanol and 90 ml of water was heated at reflux for 3.5 hours, diluted with 45 ml of water and cooled to 22°, and the separated solid was filtered off, washed with a 1:4 mixture of ethanol/water and dried, there being obtained 35.35 g (98%) of pure 2-[3(S)-amino-2(R)-hydroxy-4-phenyl-butyl]-N-tert.butyl-decahydro-(4aS,8aS)-isoquinoline-3(S)-carboxamide, m.p. 1730-1750C.
