The present invention relates to a process for the preparation of 4-[2-[[3-(4-hydroxyphenyl)-1- rnethylpropyl]amino]ethyl]-1,2-benzenediol, a compound of formula (I), and its pharmaceutically acceptable salts. The compound of formula (I), commonly known as dobutamine, is used in therapy as a cardiotonic for treating cardiac insufficiency. The process for preparation of a compound of formula (I) or its pharmaceutically acceptable salts comprises subjecting 3,4-bis(arylmethyloxy)-N-[3-(4-arylmethyloxy)-1 -methylpropyl]-β- phenethyl amine, a compound of formula (V), wherein R is independently selected from hydrogen, (C1-C6)alkyl, O-(C1-C6)-alkyl, aryl, O-aryl, aralkyl, halogen and hydroxyl, to catalytic hydrogenolysis.
