YieldReaction ConditionsOperation in experiment
26 parts of the compound (b-5) and 96 parts of a 25% sodium hydroxide aqueous solution were dissolved in 208 parts of methanol to prepare a coupler solution. On the other hand, 20 parts of the compound (a-1) was dispersed in 320 parts of waterAdd ice to adjust the temperature to 5 C, add 36.3 parts of 35% hydrochloric acid aqueous solution, stir for 1 hour, add an aqueous solution prepared by adding 6.7 parts of sodium nitrite to 19.2 parts of water And stirred for 2 hours. An aqueous solution comprising 93 parts of 80% acetic acid aqueous solution, 106 parts of 25% sodium hydroxide aqueous solution and 112 parts of water was added to prepare an aqueous diazonium salt solution.The coupler solution was injected into the aqueous solution of diazonium salt at 5 C. over 30 minutes to carry out a coupling reaction. After stirring for 2 hours, disappearance of the diazonium salt was confirmed, heated to 60 C., filtered, washed with water and dried at 80 C. for 24 hours to obtain 45 parts of the pigment represented by the formula (7). 5 parts of the pigment of the formula (7) was pulverized into 100 parts of 98% sulfuric acid and charged at 15 C. or less. Thereafter, the temperature was raised to 60 C., stirred for 2 hours, and slowly added dropwise to 2,000 parts of cold acetone prepared separately. The precipitate was filtered, washed twice with 1000 parts of cold acetone, and dried at 80 C. for 24 hours to obtain 6.1 parts of a red compound. As a result of mass spectrometry by LC-MS, it was identified that the following compound (A-5) was the main component
