Abstract

(MK-940). Convenient laboratory synthesis of 7a was provided by lithiation of 2- bromobenzhydryl methyl ether, followed by addition of 1-methyl-4-piperidone and acid- catalyzed cyclization. N-Dealkylation by standard methods afforded 9a. Synthesis of analogues was stimulated by discovery of marked inhibition of tetrabenazine-induced ptosis for lead compounds 7a and 9a. Optimal antitetrabenazine activity is associated with the S- ...
