Procedure
13.2 g (0.05 mol) of 1-(4-fluorophenyl)-2-methyl-2-(4-methylpiperazino)-propan-1-one and 6.5 g (0.065 mol) of 1-methylpiperazine are dissolved in 20 ml of dimethyl sulfoxide, and the solution is heated to about 115° C. together with 6.9 g (0.05 mol) of potassium carbonate. After 15 hours of stirring at about 115° C. the suspension is cooled down and is poured at about 60° C. onto ice. The crystals are filtered off and are recrystallised twice from ethyl acetate. Melting point 133°-136° C.
