Versuchsvorschrift

To a solution of salicylaldehyde (2 ml) in acetonitrile (20 ml) was added K2CO3 (5.71 g), followed by N-(2-chloroethyl)morpholine hydrochloride (3.5 g) and then the mixture was stirred at room temperature for 2 hours, then at reflux overnight. The reaction mixture was cooled to room temperature, filtered, and the filtrate was concentrated in vacuo to afford 2-[2-(4-morpholinyl)ethoxy]benzaldehyde, as a yellow oil.
