Abstract
A process for the preparation of substituted N-aminoalcohil-benzamidas, characterized by reducing a substituted N-aminoalcohil-benzamlda represented by the following general formula: **(See formula)** where W is an alcohol group, R1, R2 and R3 represent a hydrogen atom or an alcohol group, R4 is an amino group protected by a protecting group that can be isolated by reduction, and X represents a hydrogen or halogen atom; or a salt thereof; to thereby obtain a substituted N-aminoalcohyl-benzamide represented by the following general formula: **(See formula)** where W, R1, R2, R3 and X are as defined above, or a salt thereof.
