~25wt-, preferably! -20 weight ratio is mentioned. Furthermore, if the concentration of the inorganic acid salt in the aqueous solvent is lower than the above range, the formation of by-products such as diacyls may not be sufficiently suppressed, and conversely, if it is higher than the above range, is preferable since the raw material /-lower alkoxy-2°cudiaminobenzene becomes difficult to dissolve and the acylation reaction itself does not proceed well.

Since the concentration of the acid salt was particularly low, it was not possible to sufficiently suppress the production of by-products such as diacyls.
