Procedure
A 20 ml sample of N,N-dimethylformamide (DMF) was cooled to 0° C. for 1 hour and at 25° C. for 1 hour, then N,N-dibutylaniline was added slowly. The reaction mixture was heated at 90° C. for 16 hours, then cooled and poured onto 50 g of ice. A brown oil separated which was taken up in dichloromethane. The extract was washed with saturated aqueous bicarbonate then with water containing a little ammonium chloride, dried (MgSO4), and the solvent was removed at reduced pressure. The brown, oily residue was distilled in vacuo to product 6.65 g (58%) of a yellow liquid.
