3.5 ml of toluene were added to 855 mg (3.5 mmol) of 2-(6-methyl-quinolin-2-yl)benzonitrile obtained in Reference Example 8. To the mixture were further added 0.24 g (0.68 mmol) of sodium azide and 1 ml (3.83 mmol) of tributyltin chloride. After heating under reflux for 45 hours, the mixture was allowed to cool and diluted with 7 ml of toluene. To the mixture were added 0.4 ml (4 mmol) of a 10 N sodium hydroxide aqueous solution and 1.01 g (3.61 mmol) of tritylchloride with stirring. After stirring at room temperature for 1.5 hours, 15 ml of hexane were added to the mixture and the solid material was collected by filtration. The thus obtained solid material was washed with 10 ml of water twice and then 5 mls of methanol three times. The filter cake was dried under vacuum to obtain 1.36 g of 5-[2-(6-methylquinolin-2-yl)phenyl]-2-triphenylmethyl-2H-tetrazole.
