To a 20 L round bottom flask was added isobutyric acid (1300 mL, 14 mol), and an aqueous solution of 25% tetramethylammonium hydroxide (5 L, 14 mol). The water was removed under reduced pressure and azeotroped with toluene (2×2 L) to leave the product (13) as an amber liquid, which was used without further purification.
