Reaction Steps

9 g (19.762 mmol) of 2-amino-6-({[2-(4-chlorophenyl)-1,3-thiazol-4-yl]methyl}sulphanyl)-4-phenylpyridine-3,5-dicarbonitrile are initially charged in 200 ml of acetonitrile, 7.98 ml (59.285 mmol) of isoamyl nitrite and 7.97 g (59.285 mmol) of copper(II) chloride are added and the mixture is stirred at 60° C. for 4 hours. 1N Hydrochloric acid is added to the mixture, and the precipitated solid is filtered off. It is purified on a silica gel column (mobile phase: toluene). This gives 5.98 g (63% of theory) of the target compound.
