Reaction Steps

144 g (2 mols) of isobutyraldehyde were added dropwise to a solution of 92 g (1 mol) of aniline, 250 ml of methylene chloride, 2 ml of dimethylbenzylamine and 150 g of anhydrous magnesium sulphate at 0° C. in the course of 1 hour, whilst stirring. The mixture was further stirred at from 0° to 10° C. for 5 hours and was filtered, and the residue was rinsed with 200 ml of methylene chloride. The combined organic phases were freed from solvent, in vacuo, at from 30° to 40° C. 155 g of crude N-isobutylideneaniline were obtained and were directly further reacted.
