Reaction Conditions

Reaction Steps

In one of the preferred embodiments 4-bromomethyl-2′-cyanobiphenyl, L-valine methyl ester, potassium carbonate and potassium iodide are taken in acetonitrile. The reaction mixture was stirred at about 40-45° C. for about 3 to 4 hours and the solvent was removed under vacuum. Water and xylene was added to reaction mass and the organic layer was separated. A solution of oxalic acid was added to the organic layer and stirred for about an hour at ambient temperature to give N-[(2′-cyanobiphenyl-4-yl)methyl]-(L)-valine methyl ester oxalate salt.
