Abstract

An efficient and scalable synthesis of a glycine transporter inhibitor is presented. The key steps in the synthetic sequence are the formation of a spirocyclic imidazolidinone from an α- amino nitrile and a cyclic ketone and an arylation of 4-methyl imidazole under 'ligandless' Ullmann coupling conditions.
