The present invention is directed to a novel, high yield method for preparing 2-imidazol-1-yl-4-methyl-6-pyrrolidin-2-yl-pyrimidine, particularly to a method of preparing 4-(1-alkylpyrrolidin-2-yl)-2-(1H-imidazol-1-yl)-6-methylpyrimidine, more particularly, 2-(2-(2-(1H-imidazol-1-yl)-6-methylpyrimidin-4-yl)pyrrolidrn-1-yl)-N-(benzo[d][1,3]dioxol-5-yh-nethyl)-N-methylethanamine. These compounds and pharmaceutical compositions thereof are inhibitors of nitric oxide synthase, are selective for inducible nitric oxide synthase, and are useful in treating diseases and disorders including inflammation and pain.

We have identified and synthesized a series of imidazole containing dimerization inhibitors of inducible nitric oxide synthase (iNOS). The necessity of key imidazole and piperonyl functionality was demonstrated and SAR studies led to the identification of compound 35, which showed a dose dependant inhibition in multiple pain models, including tactile allodynia induced by spinal nerve ligation (Chung model).
