Versuchsvorschrift

Sodium azide (390 mg) was dissolved in 30 ml of methanol and cooled at −78° C., 6.0 ml of a methanolic solution of 740 mg of 1-fluoropyridinium triflate was dropped thereinto and the mixture was stirred for 4 hours. The solvent was evaporated in vacuo and the residue washed with 50 ml of diethyl ether to give 296 mg of the title compound in an ark oily crude product.
