Sodium Acetate → HCID 19976946, compound

Participants

Reaction Steps

To 35 ml of dichloromethane, were added 1.73 g (7.42 mmol) of 3-phenyl-5-(1-hydroxybutyl)isothiazole, 1.1 g (13.4 mmol) of sodium acetate and 2.88 g of "Frolisil" (trade mark). While the resultant mixture was vigorously stirred at room temperature, 2.88 g (13.4 mmol) of pyridinium chlorochromate were added at once. After the reaction mixture was stirred for 2 hours, an insoluble material was filtered off and the solvent was then distilled off. The residue was purified by silica gel chromatography (eluent: 20:1 n-hexane/ethyl acetate), whereby 3-phenyl-5-butyrylisothiazole was obtained as colorless crystals.
