Abstract: N,N,N',N'-Tetramethyl-4,4'-diaminodiphenylmethane, 6-methylcodeine, 17-norcodeine, α-codeimethine, and (3E)-O-dichlorovinylmorphine were found in the crude codeine obtained from morphine by methylation with trimethylphenylammonium hydroxide. A liq.-chromatog. method, employing column packed with reverse C-18-type phase, or alternatively gas-chromatog. one on XE-60/Chromaton N AW-DMCC were worked out for detn. of these products.
