[0173] Synthesis Example 1-1: Synthesis of 3,4,6-trichloro-5-(4-methoxy-2-methyl-phenoxy)-phthalonitrile
[0174] 3,4,5,6-tetrachlorophthalonitrile (3,4,5,6-tetrachlorophthalonitrile) (5 g), 4-methoxy-2-methylphenol (4-methoxy-2-methylphenol ) (3.12 grams), K 2 CO 3 (3.9 g) and N,N-dimethylformamide (25 mL) were placed in a 100 mL flask and then heated at 70°C while stirring. When the reaction was complete, EA (ethyl acetate) was used for extraction. After extraction, a solid was obtained by concentration. Herein, the obtained solid was dissolved in a small amount of dichloromethane, washed several times with hexane, filtered and dried under vacuum to obtain 3,4,6-trichloro-5-(4-methoxy-2- Methyl-phenoxy)-phthalonitrile.
Synthetic example 1-2
[0175] Synthesis Example 1-2: Synthesis of 4-(2-tert-butyl-4-methoxy-phenoxy)-3,5,6-trichloro-phthalonitrile
[0176] 3,4,5,6-tetrachlorophthalonitrile (5 grams), 2-tert-butyl-4-methoxyphenol (4.07 grams), K 2 CO 3 (3.9 g), N,N-dimethylformamide (25 mL) were placed in a 100 mL flask and then heated at 70°C while stirring. When the reaction was complete, EA (ethyl acetate) was used for extraction. After extraction, a solid was obtained by concentration. Herein, the obtained solid was dissolved in a small amount of dichloromethane, washed several times with hexane, filtered and dried under vacuum to obtain 4-(2-tert-butyl-4-methoxy-phenoxy)- 3,5,6-Trichloro-phthalonitrile.

[0177] Synthesis Example 1: Synthesis of compounds represented by Chemical Formula 4
[0178]3,4,6-trichloro-5-(4-methoxy-2-methyl-phenoxy)-phthalonitrile (2 g), 1,8- Diazabicycloundec-7-ene (1.04 g) and 1-pentenol (10 g) were placed in a 100 ml flask, and then heated at 90° C. to dissolve the solid, zinc acetate (0.25 g) Thereto was added, and the mixture was heated at 140° C. while stirring. When the reaction was complete, the precipitate was confirmed from methanol, filtered and dried in vacuo. The dried solid was purified by column chromatography. After purification, dichloromethane was appropriately added to the obtained solid to dissolve it, and methanol was added thereto for crystallization. The crystalline solid was filtered and dried in vacuo to obtain the compound represented by Chemical Formula 4.
