実験手順

A mixture of 3,5-dimethyl-4-(2,2,3,3,3-pentafluoropropoxy)pyridine-1-oxide (2.5 g) and dimethyl sulfate (1 ml) was heated at 120° C. for 30 minutes and methanol (12.5 ml) was added, after which a solution of ammonium persulfate (4.3 g) in water (20 ml)-methanol (10 ml) was added dropwise at 80° C. over a period of 30 minutes and the mixture was stirred for 30 minutes. After concentration, ice was added and the mixture was neutralized with sodium carbonate, and then was extracted with chloroform. After drying the extract over sodium sulfate, the solvent was evaporated to give 2.2 g of 3,5-dimethyl-2-hydroxymethyl-4-(2,2,3,3,3pentafluoropropoxy)pyridine as oil.
