Dimethyl 5-aminoisophthalate (Aldrich, 4.40 g, 21.0 mmol) is suspended in dry tetrahydrofuran (100 mL) in a 250 mL round bottom flask under an inert atmosphere. The dimethyl 5-aminoisophthalate suspension is cooled to 0° C. for at least 30 min., and an ice cold suspension of 2-decyltetradecanoyl chloride in of dry tetrahydrofuran (80 mL) is added slowly, dropwise. The reaction is then allowed to slowly warm to room temperature and stir overnight. Deionized water (10 mL) is added and the tetrahydrofuran is removed by rotary evaporation. The crude residue is then dissolved in 250 mL of ethyl acetate, and is washed with 3 successive 100 mL portions of deionized water. The ethyl acetate is then removed from the organic phase by rotary evaporation and the product is dried in vacuo to give crude dimethyl 5-(2′-decyltetradecanamido)isophthalate (12.56 g) as a pale yellow solid.
