preparation example 1
[0180] Preparation Example 1: Preparation of Compound (2)
[0181]
[0182] Preparation of Compound A
[0183] Add 2-aminonaphthalene-1-aldehyde (5.0g, 29.2mmol), 1-acetylnaphthalene (4.1mL, 35.1mmol), potassium hydroxide (3.3g, 58.4mmol) and ethanol (100mL) into the reaction vessel, and the mixture Stir at reflux under an argon atmosphere. When the reaction was completed, the reactant was cooled to room temperature, and an excess aqueous ammonium hydroxide solution was added thereto. The mixture was extracted with methyl chloride, and the extract was filtered under reduced pressure. Purification by column chromatography gave Compound (A) (4.8 g, 64%).
[0184] Preparation of compound (B)
[0185] Compound (A) (4.0g, 15.7mmol) and iridium chloride (2.1g, 7.1mmol) were dissolved in 2-ethoxyethanol (38mL) and distilled water (13mL), and the solution was stirred at reflux in an argon atmosphere for 24 Hour. When the reaction was complete, the reaction mixture was cooled ...
