Reaction Steps
484 parts of N-ethylaniline, 106 parts of sodium carbonate and 254 parts of 2,2,2-trifluoro-ethyl tosylate are heated for 48 hours at 190°-200° C. The cooled reaction mixture is diluted with 1000 parts by volume of distilled water and acidified with sulphuric acid until it is distinctly acid to Congo red paper. The N-ethyl-N-(2,2,2-trifluoro-ethyl)-aniline which is formed is then steam distilled. The lower organic layer of the distillate is separated and subjected to distillation under reduced pressure. 182 parts of N-ethyl-N-(2,2,2-trifluoro-ethyl)-aniline are thus obtained, distilling at 53°-54° C. under 1 mm of mercury, of which the elementary analysis is as follows:
