Participants

Reaction Steps

Diketene (1.48 mL, 19.2 mmol, 1.30 equiv) was added to a solution of 1-(3-hydroxypropyl)piperidine (2.12 g, 14.8 mmol, 1.00 equiv, Leonard, N. J.; Musker, W. K. J. Am. Chem. Soc. 1960, 82, 5148) in toluene (30 mL), and the mixture was stirred under argon for 72 hours at room temperature. Removal of solvent gave 3.52 g (100%) of light brown, viscous oil, which was characterized spectroscopically and used for the next reaction without purification.
