PROCESS FOR THE PREPARATION OF AROMATIC THIOL DERIVATIVES BY HYDROGENATION OF DISULFIDES

摘要

The application relates to the preparation of thiophenols by reacting the corresponding disulfide with hydrogen in the presence of a heterogeneous transition metal hydrogenation catalyst. If the reaction is carried out in the presence of an acylating agent such as a carboxylic acid anhydride or halide, an acylated thiophenol is obtained. The pharmaceutically active compound S - [ 2 - [ 1 - ( 2 - ethylbutyl) cyclohexylcarbonylamino] -phenyl] 2 -methylthiopropionate is produced via said process.
