The anhydride from step 2 (8.0 g) was mixed with 30 mL of water and 30 mL of 2-propanol and stirred at 40 for 4.25 hr. After about 2 hr there was a clear solution. The solvent was evaporated under vacuum (2 mm) at 25. The oil remaining was evaporated with 10 mL of water to remove any residual 2-propanol and acetic acid. An almost colorless oil weighing 6.8 g was isolated.
