참여 물질

반응 단계

To a suspension of 2.94 g (7.31 mmol) of 1,2-dihydro-3-methyl-1-[6-(phthalimido)hexan-1-yl]-1,4,7b-triazacyclopent[cd]inden-2-one in 80 ml of ethanol was added 1.10 g (22.0 mmol) of hydrazine.monohydrate. The mixture was heated for 2 hours under reflux. After cooling, the resulting precipitates were filtered off.
