Procedure
2-(4-Chlorobenzyl)1,3-bis(1,2,4-triazol-1-yl)2-propanol (0.318g) was added to a solution of diethylamino sulphur trifluoride (0.128g) in chloroform (15ml), and the resulting yellow solution was stirred at room temperature for 3.5 hr. The mixture was then poured into water and the organic layer was separated, washed with water, dried, and evaporated to dryness. The yellow oil so obtained was purified by chromatography on a 25cm silica (Merck "Lobar") column, eluting with 3% v/v methanol in chloroform, to give a colourless oil which was crystallised from diethyl ether to give 2-(4-chlorobenzyl)-2-fluoro-1,3-bis(1,2,4-triazol-1-yl) propane, m.p. 161-163°.
