Enzalutamide, a second-generation antiandrogen, has been developed for the treatment of castration-resistance prostate cancer. We synthesized the deuterated analogues 6 and found that it showed higher drug exposure and thus stronger antitumor potency in preclinical settings. Compound 6 is being developed clinically for the potential to be differentiated from enzalutamide through reduced dosages and a higher safety margin.

A novel method for synthesizing deuterated amides and deuterated sulfonamides includes the following steps: (1) adding a compound M, DMAP, R
3
—X to a solvent to obtain a compound N after a reaction is complete; and (2) adding the compound N, R
4
—NH—R
5
, or a salt and base thereof to a solvent, and purifying after a reaction is complete to obtain a compound I.
