Versuchsvorschrift

A mixture of N-propylaniline (24 parts), 2-ethylhexyl bromide (58 parts), anhydrous potassium carbonate (42 parts) and dry N,N-dimethylformamide (50 parts) was stirred at 125° C. for 16 hours. The cooled reaction mixture was poured into water (250 parts), the organic phase separated and washed with water (2×200 parts) and dried at 90° C. and 15 mmHg to yield N-(2-ethylhexyl)-N-propylaniline (49 parts, 89%). Acetic anhydride was added to this to make a total of 69.5 parts.
