Reaction Steps

To an N,N-dimethylformamide solution (170 mL) of 4-[4-(4-fluorophenyl)piperazin-1-yl]-1,3,5-triazin-2(1H)-one (8.48 g, 30.8 mmol) synthesized in Reference Synthesis Example 3, 4-chlorobenzyl bromide (6.32 g, 30.9 mmol) and potassium carbonate (5.11 g, 37.0 mmol) were added and the resultant mixture was stirred at 50° C. for 1 hour and at 70° C. for 3 hours. To the reaction solution, 4-chlorobenzyl bromide (1.90 g, 9.25 mmol) and potassium carbonate (2.13 g, 15.4 mmol) were added and the resultant reaction solution was stirred at 70° C. further for 2 hours. After the completion of the reaction, water was added to the reaction solution and a resultant solid was filtered and was dried under reduced pressure. The resultant solid was suspended in ethyl acetate and the suspension was stirred at room temperature for 10 minutes. The solid was filtered and was dried under reduced pressure. These operations from suspending of the solid to the second drying of the solid were performed twice to obtain the title compound (6.49 g, yield: 53%).
