[0071] Preparation of Intermediate I-1:

[0072] 2,4,6-Trichloro-1,3,5-triazine (100 g, 542.27 mmol) and 800 ml of anhydrous tetrahydrofuran were put into a 3 L reaction flask, and stirred at 0° C. under nitrogen. 97.93ml (1mol / L) of phenylmagnesium bromide (obtainable from the reaction of bromobenzene and metal magnesium) was added dropwise thereto, and the temperature was naturally raised to room temperature, and stirred for 1 hour. A 2 mol / L hydrochloric acid aqueous solution was added to the above reaction liquid, followed by washing with dichloromethane and ultrapure water. After drying over anhydrous magnesium sulfate and filtering through silica gel, the filtrate was concentrated under reduced pressure, and recrystallized with dichloromethane and n-heptane to obtain intermediate I-1 (98 g, yield 80%).
