A novel and highly efficient synthetic approach has been developed for the synthesis of deuterium-labeled olopatadine-d6 using inexpensive and commercially available dimethyl sulfate-d6 at the stage of alkylation of primary amine intermediate. The proposed synthetic path makes it possible to avoid the use of expensive labeled reagents such as dimethyl amine-d6 used as labeled precursor in the traditional synthetic route. The structure of the obtained olapatadine-d6 has been confirmed by 1H NMR and mass spectral data.
