1-[2-Hydroxy-3-propyl-4-(4-bromomethylphenylmethoxy)phenyl]ethanone (6.4 g; 0.017 m) and potassium thiocyanate (3.3 g; 0.034 m) were dissolved in dry dimethylsulphoxide (60 ml) and stirred at room temperature for 4 hours. The solution was then poured onto water, stirred and filtered to give a white solid; dried at 60° C. under reduced pressure. Recrystallised from ethanol to give a white crystalline solid m.p. 110°-111° C.
