Using amino C acid, m-toluidine, cyanuric chloride and m (2-sulfate ethyl sulfone group) aniline as raw materials, the amino C acid is first diazotized, coupled with m-toluidine, and then With cyanuric chloride for the first condensation, and finally with m (2-sulfate ethyl sulfone group) aniline for the second condensation to obtain the product. The finished product is salted out, filtered and dried.
