Procedure

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 (4b) as an amber liquid, which was used without further purification.
