실험 절차
A mixture of 82.5 grams (g) of 2-fluoro-6-(trifluoromethyl)pyridine (0.5 mole), 65 g of sodium azide (1.0 mole) and 400 milliliters (ml) of dimethylsulfoxide (DMSO) was heated to a temperature of 80° C. for 18 hours. The mixture was allowed to cool and then poured into 1500 ml of ice water. This resulting mixture was then extracted 4 times with 300 ml of pentane each time. The pentane extracts were combined, washed with 500 ml of a saturated NaCl solution and dried with MgSO4. The pentane was then carefully evaporated leaving 67 g of the desired 2-azido-6-(trifluoromethyl)pyridine as a light yellow oil having an RI of 1.4771 @25° C.
