Procedure
Suspend 2 mmol (570 mg) of 6-chloro-5-benzyl-3-phenyl-1,2,4-triazine obtained in Step A of Example 57 in 40 ml of butanol, and add 4 equivalents of 1-(3-chlorophenyl)piperazine. Heat for 12 hours at 120° C., concentrate the solution, take up in ether, filter the resulting precipitate and recrystallise it from ethanol.
