Abstract

A concise and practical synthesis of a 1, 4-diaryl-5-methyl-1, 2, 3-triazole is described. A mGluR1 antagonist 1 was prepared with one-pot operation by the Negishi coupling reaction between two building blocks, 5-bromophthalimidine (2) and 1-aryl-5-methyl-4-triazolylzinc (3- Zn). Bromide 2 was synthesized via N-selective cyclization of o-hydroxymethylbenzamide 8 easily prepared from phthalide 4. Zinc species 3-Zn was generated in situ by ...
