Using DSD acid, amino C acid, cyanuric chloride and p-methylo-aminoanisole as raw materials, firstly, cyanuric chloride and DSD acid are condensed for the first time, and then with p-methylo-aminoisole For the second condensation, the amino C acid is diazotized, and the product is coupled with the aforementioned condensate. The finished product is salted out, filtered, dried and crushed.
