( R )- N -[( R )-1-(2-Hydroxy-5-methylphenyl)-2-phenylethyl]-2-methyl-1-phenylpropylammonium chloride

In the title compound, C 25 H 30 NO + ·Cl - , the molecules are linked by a combination of-intermolecular N-H···Cl and O-H···Cl hydrogen bonds and intramolecular N-H···O hydrogen bonds. The absolute configuration of the new stereogenic centre (the C atom adjacent to the N atom on the phenol side) is determined to have an R configuration.
