Sodium Chloride → HCID 19020727, compound

Participants

Reaction Steps

100 ml (72.3 mmoles) of a 10% w/v aqueous solution of potassium carbonate were added to a solution of 15.0 g (59.6 mmoles) of 5-(m-chlorophenyl)-3-(2,3-epoxypropoxy)isoxazole (prepared as described in Preparation 2) in 50 ml of acetonitrile, and the mixture was heated under reflux for 3 hours. At the end of this time, the reaction mixture was cooled by allowing it to stand, and then 400 ml of a 10% w/v aqueous solution of sodium chloride were added thereto, and the mixture was extracted twice, each time with 400 ml of ethyl acetate. The combined organic extracts were dried over anhydrous magnesium sulfate, and the solvent was removed by distillation under reduced pressure. The resulting residue was then purified by column chromatography through silica gel, eluted with a 1:2 by volume mixture of benzene and ethyl acetate, to give 13.2 g (yield 82.5%) of the title compound as a colorless amorphous powder, melting at 92°-93° C.
