실험 절차

A dry flask containing N-(4-chlorobenzyl)-4-hydroxy-6-(4-morpholinylmethyl)-3-quinolinecarboxamide (0.20 gm) from Preparation No. 40 in dry THF (5 mL) under an argon atmosphere is added triphenylphosphine (393 mg), 1,4-butyne diol (0.45 gm) and diethyl azodicarboxylate (0.18 mL). The mixture is stirred at room temperature overnight, concentrated under reduced pressure and adsorbed onto silica gel. The crude product is purified by flash column chromatography eluting with 2% to 6% methanol in dichloromethane and then by recrystallization from methanol-acetonitrile to afford 0.16 gm of the title compound as a white solid.
