Reaction Steps
First, 13.02 g of 1,5-pentanediol, 2.40 g of sodium hydroxide (powdery), 1.14 g of benzyltriethylammonium chloride, and 100 ml of tetrahydrofuran were placed in a reaction vessel, to which 8.18 g of chloroacetone O-tert-butyloxime was slowly added dropwise with stirring under heating under reflux. After further stirring for 8 hours, the reaction mixture was poured into diluted hydrochloric acid, and extracted twice with ethyl acetate. The ethyl acetate layers were combined, washed with diluted hydrochloric acid and water in this order, dried over anhydrous magnesium sulfate, and concentrated to give a crude product. This crude product was subjected to silica gel chromatography, which afforded 6.79 g (yield, 59%) of 5-hydroxypentyloxyacetone O-tert-butyloxime, nD20.0 1.4493.
