Reaction Conditions

Reaction Steps

Into a 500 ml round bottom flask 30 g of 2-cyclohexylpropionic acid and 200 ml of ether were charged and cooled to 0° C. After 100 g of isobutene gas was introduced, 0.5 g of sulfuric acid was charged into the mixture, the mixture was then stirred at 0° C. for 40 hours. The reaction mixture was washed with water and distilled under reduced pressure to obtain 4.5 g of tert-butyl 2-cyclohexylpropionate having a woody and floral odor (yield: 11%, purity: 98.7%).
