1-(1-propenyl)-piperidine (9.4 g; 75.07 mmol) and 4-fluorophenylazide (10.3 g; 75.07 mmol), prepared as described in example 1, were admixed at 0° C. and the resultant mixture was kept at room temperature for 54 hours in the absence of light. The obtained solid mass was collected with petroleum ether and filtered obtaining the title compound (6 g). The mother liquor was evaporated and the resultant crude compound was purified by chromatography on silica gel (230-400 mesh), eluent petroleum ether:ethyl acetate=9:1, obtaining further title compound (m.p. 75° 76° C.).
