실험 절차

0.28 g (0.007 mol) of solid sodium hydride is added to a suspension of 0.5 g (0.00175 mol) of 1,4-diketo-2,5-dihydro-3,6-diphenyl-pyrrolo[3,4-c]pyrrole in 17 ml of tetrahydrofuran in an argon atmosphere. After the resulting mixture is stirred for 24 hours, 0.67 ml (0.007 mol) of n-butyl chloroformate is added thereto, and the resulting suspension is stirred overnight. The mixture is filtered, and the filtrate is concentrated under reduced pressure. The residue is taken into water/diethyl ether, and the organic phase is dried over MgSO4 and then concentrated under reduced pressure. The residue is taken into n-hexane, and the yellow powder precipitated is collected by filtration, washed with a small amount of n-hexane to give 0.62 g (73% of the theoretical value) of N,N'-bis(n-butoxycarbonyl)-1,4-diketo-2,5-dihydro-3,6-diphenyl-pyrrolo[3,4-c]pyrrole as a yellow fluorescent powder.
