Ethyl Acetate → 5,5-Dimethyl-3-naphthylcarbonyl-1,3-oxazolidine-2,4-dione

Participants

Reaction Steps

5,5-Dimethyl-2,4-oxazolidinedione potassium salt (84 mg) was suspended in tetrahydrofuran (1 mL), 1-naphthoyl chloride (95 mg) was added, and the mixture was stirred at room temperature overnight. To the reaction solution was added 4 mL of ethyl acetate, and the solution was filtered with a membrane filter (0.25 μm). The resulting organic layer was purified by silica gel chromatography (hexane:ethyl acetate=2:1), and further recrystallized from ethyl acetate/IPE to obtain 61 mg of white crystals.
