Procedure

A mixture of 6.84 g. of 2-chloro-4,6-bis[(1,1,2,2-tetramethylpropyl)amino]-s-triazine and 7.69 g. of N-(p-methoxyphenyl)piperazine (prepared from the commercially available dihydrochloride salt) in 150 ml. of chlorobenzene is refluxed for 5 hours and then cooled. The reaction mixture is washed with two 25 ml. portions of water. The organic layer is dried over anhydrous potassium carbonate and magnesium sulfate and the solvent is stripped with a water pump. The residual amber oil is crystallized by slurrying in isopropanol. Recrystallization from 150 ml. of propanol (using charcoal for decolorization) gives the desired product as a white solid, m.p. 155°-157° C.
