Reaction Steps

1,1-bis(4-chlorophenyl)-2-(1H-1,2,4-triazol-1-yl)propan-1-ol (2.0 g) from Example 3xi was dissolved in dry toluene (40 ml), and a catalytic amount of p-toluene sulphonic acid added. The mixture was refluxed in a round bottom flask fitted with a soxhlet extractor filled with molecular sieves (4A) and condenser. Reflux was continued until there was no starting material remaining on tlc. The mixture was poured into water and extracted, washed with water (3X) then dried over anhydrous magnesium sulphate and evaporated on a rotary evaporator. The product was purified by chromatography on silica gel eluted with CH2Cl2 /ethylacetate (3:2). 1,1-bis(4-chlorophenyl)-2-(1H-1,2,4-triazol-1-yl)prop-1-ene was obtained as a white solid (1.0 g) by recrystallisation from hexane.
