Reaction Steps

Chromic acid (105.4 mg, 1.05 mmol, 1.2 eq) was dissolved in acetic acid (2 ml), and a solution of 3-(1,1-dimethylheptyl)benzaldehyde (205 mg, 0.878 mmol) in acetic acid (2 ml) was added to the solution under ice-cooling, which was followed by stirring for 2 minutes. The mixture was further stirred at room temperature for 30 minutes. Conc. sulfuric acid (2 drops) was added, and the mixture was stirred for 3 hours. To this reaction mixture, water (10 ml) was added, and the mixture was extracted twice with ethyl acetate (10 ml). The organic layers were combined, washed with saturated brine (20 ml), and dried over anhydrous sodium sulfate. The drying agent was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by column chromatography (n-hexane/ethyl acetate=2/1) to give 3-(1,1-dimethylheptyl)benzoic acid (205 mg, 99.0%).
