실험 절차

A mixture of N-(2-ethylhexyl)aniline (8.9 parts), 1-bromopropane (7.4 parts), anhydrous potassium carbonate (11 parts) and N,N-dimethylformamide (30 parts) was stirred at 125° C. for 24 hours. An additional quantity of 1-bromopropane (5 parts) was added and the mixture stirred for a further 18 hours at 125° C. The cooled mixture was filtered and poured into water. The product was extracted into dichloromethane and evaporated to yield N-(2-ethylhexyl)-N-propylaniline (8.9 parts, 78%) which was reacted with acetic anhydride prior to use to remove any unreacted starting materials.
