A solution of osmium tetroxide in acetone was treated with N-methylmorpholine in aqueous acetone. 4-Allyl-2-fluoro-1-triphenylmethylimidazole was added, and the mixture stirred at ambient temperature overnight. Reductive work-up with sodium metabisulphite and magnesium trisilicate, followed by extraction into ether, gave 4-(2,3-dihydroxypropyl)-2-fluoro-1-triphenylmethylimidazole, having the following n.m.r. in CDCl3 : 2.6 (d, 2H); 3.6 (m, 2H); 3.9 (m, 1H); 6.3 (s, 1H); 7.0-7.5 (m, 15H).
