Using DSD acid, 2-amino -4-methyl anisole, amino C acid, cyanuric chloride and p-aminobenzene sulfonic acid as raw materials, DSD acid is first condensed with two molecules of cyanuric chloride, and then Amino C acid is diazotized, coupled with 2-amino -4-methyl anisole for the second condensation, and finally with p-aminobenzene sulfonic acid for the third condensation.
