MÉTODOS PARA A PREPARAÇÃO DE DERIVADOS DE N-ISOBUTIL-N-(2-HIDRÓXI-A-AMINO-4-FENILBUTIL)-P-NITROBE NZENOSSULFONILAMIDA

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-isobutylamino-propyl)-carbamic acid derivative is reacted with a p-nitrophenylsulfonyl halide to provide the desired product in a high yield and degree of purity.
