2-[N-(2-hydroxyethyl)-N-methyl]-amino}-methylbenz- hydrol, which is used as an intermediate when producing 3,4,5,6-tetrahydro-5-methyl-1-phenyl-1 H-2,5-benz- oxazocine-hydrochloride or nefopam, which is used as a muscle relaxant, an analgesic or antidepressive drug, is advantageously made by reacting 2-chloromethylbenzophenone with methylethanolamine, and reducing the thus produced 2-[N-(2-hydroxyethyl)-N-methyl]-amino}- methylbenzophenone with sodium borohydride.
