Versuchsvorschrift

A solution of 2-methylhexanoic acid (20 g, 153 mmol) in methanol (500 mL) was treated with concentrated sulfuric acid (8.0 mL) and heated to 50° C. for 16 h. The reaction was diluted with water and extracted with ether. The combined organic layers were dried and concentrated to afford 20.57 g (93%) of methyl 2-methylhexanoate as a colorless liquid.
