Procedure
0.69 g(0.03 mol) of metallic sodium was dissolved in 100 ml of absolute ethanol and then 5.97 g(0.03 mol) of 1,4-dichlorophthalazine was added thereto and completely dissolved. The reaction solution was stirred for one hour at 50±10° C. and then treated according to the same manner as Preparation 5 to obtain the title compound as a white needle crystal.
