| | 4-BUTOXYANILINE Usage And Synthesis |
| Chemical Properties | CLEAR DARK BROWN LIQUID | | Uses | 4-Butoxyaniline was used in the preparation of:
- bis-4-butoxyphenyl-4,4′-(2,2′-bipyridyl)carbamide
- 1-(4-butoxyphenyl)-3-(6-methyl-3-oxo-2-phenyl-2,3-dihydropyridazin-4-yl)urea
| | General Description | 4-Butoxyaniline undergoes low-pressure hydrogenation in the presence of rhodium on alumina to yield 4-butoxycyclohexylamine. | | Synthesis | GENERAL METHOD: 1-butoxy-4-nitrobenzene (0.0270 mol) was dissolved in 70 mL of ethanol. Tin chloride (0.119 mol) was dissolved in 30 mL of ethanol and added dropwise to the reaction system. The reaction was stirred continuously at 80 °C for 2 hours. Upon completion of the reaction, the crude product was extracted twice with a solvent mixture of ethyl acetate/water (1:1, v/v) and 60 g of potassium carbonate was added to the aqueous phase to neutralize the acidic by-products. The organic phases were combined and the solvent was removed by evaporation under reduced pressure to give the yellow oily product 4-butoxyaniline. Yields ranged from 65% to 85%. For 4-butoxyaniline (3a), the 1H-NMR (DMSO-d6) data were as follows: δ 6.64 (d, 2H), 6.52 (d, 2H), 4.56 (s, 2H), 3.58 (t, 2H), 1.75 (m, 2H), 1.39 (m, 2H), 0.99 (t, 3H). The yield of 4-butoxyaniline under this experimental condition was 65%. | | References | [1] Science China Chemistry, 2011, vol. 54, # 11, p. 1726 - 1734
