2-azidopropane

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of isopropylazide [G. A. Olah, D. J. Donovan, J. Org. Chem., 43, 860, (1978)] (54.5 g; 640.3 mmol) and 4-fluorophenylacetylene [J. B. Lambert et al., J. Am. Chem. Soc., 107, 5443, (1985)] (39 g; 325.1 mmol) was heated at 70° C. for 41 hours. The excess of isopropylazide was distilled off an the resultant crude compound was purified by chromatography on silica gel (230-400 mesh), eluent methylene chloride:acetone=39:1, giving the title compound (m.p. 54°-55° C.). The excess of isopropylazide was distilled off an the resultant crude compound was purified by chromatography on silica gel (230-400 mesh), eluent methylene chloride
