DSD acid, amino C acid, 2-methoxy-5-methylaniline and cyanuric chloride are used as raw materials. First, the amino C acid is diazotized, coupled with 2-methoxy-5-methylaniline, then the coupling product is condensed with cyanuric chloride, and finally the condensate and DSD acid are second Condensation product. The finished product is salted out, filtered and dried.
