Abstract:hexyloxyphenol (1) was synthesized with hydroquinone and 1-bromohexane as materials, by phase transfer catalyst. (1) was esterified using 3,5-dinitrobenzoyl chloride to afford 3,5-dinitrobenzoic acid-4’-hexyloxybenzene ester (2). 2 was hydrogenated with Pd/C catalyst to give the title compound 3,5-diaminobenzoic acid-4’-hexyloxybenzene ester (3). The total yield of 3 reachs 33.2%. The title compound was identified by element analysis and NMR. |
Key words:diaminobenzoic acid-4’-hexyloxybenzene ester; synthesis; NMR |
