Procedure
Sodium t-butoxide (2.86 g) was added to dimethyl sulfoxide (20 ml), and after stirring at room temperature for 50 min., tetrahydrofuran (30 ml) was added and ice-cooled. Trimethylsulfonium iodide (4.04 g) was added to the mixture, and after stirring under ice-cooling for 10 min., a solution of sodium hydroxy[2-({4-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]benzyl}oxy)pyridin-3-yl]methanesulfonate (5 g) in dimethyl sulfoxide (15 ml) was dropwise added under ice-cooling and the mixture was stirred under ice-cooling for 1 hr. and at room temperature for 1 hr. The reaction solution was poured into iced water (100 ml) and extracted twice with t-butylmethyl ether (50 ml). The organic layers were combined, washed 4 times with water (50 ml) and concentrated under reduced pressure to give 2-({4-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]benzyl}oxy)-3-oxiran-2-ylpyridine.
