実験手順

8.46 g (0.06 mole) of 1-acetyl-4-piperidone and 3 ml. of glacial acetic acid are added to a solution of 12.0 g (0.06 mole) of 1-(2-amino-4-methyl-phenyl)pyrrole [Example 16(b)] in 160 ml. of absolute ethanol. The solution is refluxed under nitrogen with stirring for 24 hours and cooled. A solid precipitates and is filtered. The solid is recrystallized from absolute ethanol to give white crystals, m.p. 212°-213° C. of 1'-acetyl-4,5-dihydro-7-methylspiro[pyrrolo(1,2-a)quinoxaline-4,4'-piperidine].
