2-(2-oxopiperidin-1-yl)acetaldehyde

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 1-(2,2-dimethoxyethyl)-piperidin-2-one (1.06 g, 5.67 mmole) in 5% aqueous tetrahydrofuran (20 mL) was heated under reflux for 1 hour. The mixture was dried with anhydrous magnesium sulfate, filtered, and concentrated to give (2-oxo-piperidin-1-yl)-acetaldehyde (0.69 g) as a pale yellow oil. was heated under reflux for 1 hour The mixture was dried with anhydrous magnesium sulfate filtered concentrated
