摘要:
A process for the preparation of N-isobutyl-N-(2-hydroxy-3-amino-4-phenylbutyl)-p-nitrobenzenesulfonylamide derivatives in which a (1-benzyl-2-hydroxy-3-isobutyl-amino-propyl)-carbamic acid derivative is reacted with a p-nitrophenylsulfonyl halide to provide the desired product in a high yield and degree of purity.
