Reaction Steps

3-tert-butyl salicylaldehyde (1) (0.70 g/3.93 mmol) and 4-ethynyl aniline (0.49 g/4.2 mmol) were dissolved in 100 ml of ethanol. Molecular sieves (3 Å, 15 g) and a few drops of glacial acetic acid were added and the mixture was stirred at room temperature for three days. After filtration over sodium sulphate and removal of the solvent, the residue was extracted several times with n-pentane. The solution was filtered again over sodium sulphate, and the solvent was removed. The title compound was obtained as a yellow powder. Yield: 43%.
