Synthetic example 1
[0305] The following reactions were carried out under nitrogen atmosphere. After placing 15.3 parts of N-methylaniline (manufactured by Tokyo Chemical Industry Co., Ltd.) and 60 parts of N,N-dimethylformamide in a flask equipped with a cooling tube and a stirring device, the mixed solution was cooled with ice. After gradually adding 5.7 parts of 60% sodium hydride (manufactured by Tokyo Chemical Industry Co., Ltd.) over 30 minutes under ice cooling, the mixture was stirred for 1 hour while raising the temperature to room temperature. At room temperature, 10.4 parts of 4,4'-difluorobenzophenone (manufactured by Tokyo Chemical Industry Co., Ltd.) was gradually added in small amounts to the reaction liquid and stirred for 24 hours. The reaction solution was gradually added to ice water 200 in small amounts, and then left to stand at room temperature for 15 hours, and water was removed by decantation to obtain a viscous solid as a residue. After adding 60 parts of methanol to thi...

[0317] 20 parts of the compound represented by the formula (1x) and 200 parts of N-propyl-2,6-dimethylaniline (manufactured by Wako Pure Chemical Industries, Ltd.) were mixed under light-shielding conditions, and the resulting solution was stirred at 110° C. for 6 hours . After cooling the obtained reaction liquid to room temperature, it added to the mixed liquid of 800 parts of water and 50 parts of 35 weight% hydrochloric acid, and stirred at room temperature for 1 hour, and crystallization precipitated. The precipitated crystals were obtained as suction filtration residues and dried to obtain a compound represented by formula (1-32).

Synthetic example 3
[0321] After adding 65 parts of water to 7.5 parts of 2-amino-4-methylsulfonyl-6-nitrophenol (CAS No. 101861-04-5), 1.3 parts of sodium hydroxide were added and dissolved. Under ice cooling, 6.1 parts of 35% sodium nitrite (manufactured by Wako Pure Chemical Industries, Ltd.) aqueous solution was added, followed by gradually adding 19.4 parts of 35% hydrochloric acid to dissolve and stir for 2 hours to obtain a suspension containing a diazonium salt. Next, an aqueous solution in which 5.6 parts of sulfuric acid amide (manufactured by Wako Pure Chemical Industries, Ltd.) dissolved in 26 parts of water was slowly added to deactivate excess sodium nitrite.
[0322] Next, 5.6 parts of 3-methyl-1-phenyl-5-pyrrolidinone (manufactured by Wako Pure Chemical Industries, Ltd.) was suspended in 70 parts of water, and the pH was adjusted to 8.0 using sodium hydroxide. Here, while appropriately adding a 10% sodium hydroxide solution so as to keep the pH in the range of 7 to 7.5, the aforem...
