実験手順
The further step of reacting the 4-[1-(1,2,4-triazole-1-yl)methyl]benzonitrile of formula II with 4-fluorobenzonitrile to yield 4-[1-(4-cyanophenyl)-1-(1,2,4-triazol-1-yl)methyl]benzonitrile of formula I, may be carried out in the presence of an organic solvent and a silicon amine. This is the same step as is described below in the second aspect of the present invention. The 4-[1-(1,2,4-triazole-1-yl)methyl]benzonitrile of formula II from the first step may be isolated with or without drying before reaction with 4-fluorobenzonitrile.
