실험 절차

In a variation to the procedure referred to in example1, 2-(2-p-tolyl-vinyl)-pyridine 1-oxide (9.8 g, 46 mmol) was reacted first with dimethylsulfate (5.8 g, 46 mmol) and then with NaCN (2.74 g, 56 mmol). After extraction and crystallization 6-(2-p-tolyl-vinyl)-pyridine-2-carbonitrile (5.8 g, 57%) was obtained as a yellow crystalline material. Mp. 137–138° C. (isopropanol), MS: m/e=220 (M+)
