N-Iodosuccinimide → HCID 23369570, compound

Participants

Reaction Steps

2-(t-Butoxycarbonyl)aminomethyl-2,3,6,7-tetrahydrofuro[2,3-f]quinoline-7-one (882 mg) and N-iodosuccinimide (756 mg) were dissolved in a solvent mixture (44 ml) of chloroform-methanol (5:1). After refluxing for 2.5 hours with heat, N-iodosuccinimide (756 mg) was added to the mixture, followed by further 2 hour refluxing with heat. Further, N-iodosuccinimide (400 mg) was added to the mixture, which was then refluxed for 1.5 hours with heat. After completion of the reaction, the solvent was distilled off, and the residue was purified by silica gel column chromatography (eluent=chloroform:methanol=200:1) to obtain 903 mg of 2-(t-butoxycarbonyl)aminomethyl-5-iodo -2,3,6,7-tetrahydrofuro[2,3-f]quinoline-7-one (73.2%). This compound was recrystallized from a solvent mixture of chloroform-n-hexane to obtain pale yellow powdery crystals (mp.: 173°-174° C.).
