    摘要: Methods for producing methadone and its resolution to produce ( R )-6-dimethylamino-4,4-diphenylheptan-3-one (( R )- methadone). Such methods producing first the precursor compound 4-(dimethylamino)-2,2-diphenylpentanitrile. Oxidation of 4-(dimethylamino)-2,2-diphenylpentanitrile with ethyl magnesium halide and hydrolysis with of the complex to form 6-dimethylamino-4,4-diphenylheptan-3-one. Resolution to the ( R )-isomer is effected by reaction with a bromocamphor salt. Once isolated the ( R )-isomer is crystallised.
