Reaction Steps

3,5-Diaminobenzoic acid (Sigma-Aldrich) was esterified using a known procedure (Electrochimica Acta 2001, 46, 3955-3962) with thionyl chloride and anhydrous methanol to give the corresponding methyl ester, methyl 3,5-diaminobenzoate. Methyl 3,5-diaminobenzoate (260.8 mg, 1.9 mmol) was dissolved in dry tetrahydrofuran (5 mL) in a 100 mL vessel under inert atmosphere. Triethylamine (0.7 mL, 4.99 mmol) was then added and the solution was cooled to 0° C. A solution of 2-decyltetradecanoyl chloride from Step 1 in dry tetrahydrofuran (10 mL) was then added slowly, dropwise. The reaction was then allowed to warm slowly to room temperature. After stirring overnight, the reaction was quenched with water and the tetrahydrofuran was removed by rotary evaporation. The crude product residue was then dissolved in diethyl ether (50 mL) and washed with deionized water (20 mL). The ether layer was separated and concentrated to give methyl 3,5-bis(2′-decyltetradecanamido)benzoate as a pale pink solid (1.17 g).
