実験手順

7.06 g (0.05 mole) of 1-acetyl-4-piperidone and 5 ml. of glacial acetic acid are added to a solution of 9.41 g (0.05 mole) of 1-(2-amino-4-methoxy-phenyl)pyrrole [Example 19(b)] in 150 ml. of absolute ethanol. The solution is refluxed for 12 hours. The volume of the solvent is reduced to about one fifth and the solution is cooled. A solid precipitates and is filtered, dried, and recrystallized from ethanol to give 1'-acetyl-4,5-dihydro-7-methoxyspiro[pyrrolo(1,2-a) quinoxaline-4,4'-piperidine], m.p. 211°-213° C.
