[0182] [Synthesis of Exemplary Compound (1)]
[0183] The aforementioned exemplary compound (1) as a dipyrromethene metal complex compound represented by the general formula (1) was synthesized by the method described below.
[0184] -Synthesis of Intermediate A-
[0185]Intermediate A of the following structural formula was synthesized by the method described in US Patent Application Publication No. 2008 / 0076044.
[0186] [chemical 7]
[0187] Intermediate A
[0188]
[0189] -Synthesis of Intermediate B-
[0190] 690 ml of acetonitrile was added to 225.8 g (0.55 mol) of intermediate body A, and it stirred under ice-cooling. To this solution, 93.5 g (0.61 mol) of o-toluoyl chloride was added dropwise. Thereafter, 52.2 g (0.66 mol) of pyridine was added dropwise, followed by stirring under ice-cooling for 1 hour, and then stirring at room temperature for 2 hours. After the reaction, the precipitated solid was filtered, and the filtrate was washed with acetonitrile and...
