Procedure

Diketene (2.54 mL, 33.0 mmol, 1.30 equiv) was added to a solution of 3-(N,N-dimethyl)aminopropan-1-ol (3.00 mL, 25.4 mmol, 1.00 equiv, Aldrich) in toluene (30 mL) and the mixture was stirred at room temperature for 70 hours. The solvent was removed to afford 4.76 g of brown oil, which was characterized spectroscopically and used for the next reaction without purification.
