Procedure

2-Nitro-4-dodecylaniline (3.06g) was dissolved in acetic acid (15ml) and propionic acid (15ml) and warmed whilst dilute hydrochloric acid (5ml) was added. The mixture was cooled to 0° C. and sodium nitrite (0.7g) was added at 0° C. The diazotised amine was then added to N-methyl-N-(2-carboxyethyl)aniline (1.79g) in water (100 ml) with dilute hydrochloric acid (3ml). Sodium acetate was added until colour developed and the mixture was stirred for 0.5 hours. The crude product was recrystallised from CH2Cl2 to give a red solid (0.2g).
