Procedure: Methyl 3,5-diaminobenzoate (260.8 mg, 1.9 mmol) is dissolved in dry tetrahydrofuran (5 mL) in a 100 mL vessel under an inert atmosphere. Triethylamine (0.7 mL, 4.99 mmol) is then added and the solution is cooled to 0° C. A solution of 2-decyltetradecanoyl chloride from Step I in dry tetrahydrofuran (10 mL) is then added slowly, dropwise. The reaction is then allowed to slowly warm to room temperature. After stirring overnight, the reaction is quenched with water and the tetrahydrofuran is removed by rotary evaporation. The crude product residue is then dissolved in diethyl ether (50 mL) and is washed with deionized water (20 mL). The ether layer is separated and concentrated to give methyl 3,5-bis(2′-decyltetradecanamido)benzoate as a pale pink solid (1.17 g). to slowly warm to room temperature the reaction is quenched with water the tetrahydrofuran is removed by rotary evaporation The crude product residue is then dissolved in diethyl ether (50 mL) is washed with deionized water (20 mL) The ether layer is separated concentrated

Procedure: A mixture of 2-chloro-3-nitropyridine (3.20 g), methyl 3,5-diaminobenzoate (3.20 g) and potassium carbonate (4.0 g) in 1,4-dioxane (60 ml) was stirred under reflux for 4 hours. After cooling, insoluble materials were removed by filtration and the filtrate was concentrated. The residue was chromatographed on silica gel column (5% methanol in chloroform) to give 2-(3-amino-5-methoxycarbonylphenylamino)-3-nitropyridine (1.12 g). under reflux for 4 hours After cooling insoluble materials were removed by filtration the filtrate was concentrated The residue was chromatographed on silica gel column (5% methanol in chloroform)

After concentration to half the volume water was added and the precipitate collected by filtration. The precipitate then was treated with sodium hydroxide solution (1 n) and dichloromethane. The organic phase then was washed with water and brine, dried (Na2SO4) and evaporated to dryness to give the title compound (13.8 g).
