Versuchsvorschrift

To a solution of 70 mg of the compound of Example 14 dissolved in 10 ml of dioxane was added 0.105 ml (3 equivalents) of 1-(2-pyridyl)piperazine and the mixture heated under reflux for 8 hours. The reaction treatment and purification were conducted as in Example 17, to obtain 86.2 mg of the desired compound (yield 97%). The maleate was obtained by converting the product to maleate in a conventional manner, followed by recrystallization from methylene chloride-ether.
