Procedure

A mixture was prepared by adding 5.0 g of 2-chloro-6,7,8,9-tetrahydropyridazino[1,6-a]benzimidazole to 30 ml of morpholine and this was stirred and heated at reflux for 24 hours. It was then poured into 200 ml of ice water. A tan solid formed and this was separated by filtration to give 2-(4-morpholinyl)-6,7,8,9-tetrahydropyridazino[1,6-a]benzimidazole melting at 187.5°-188.5° C.
