Versuchsvorschrift

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), ethyl 2-hydroxyethylsulfide (0.16 mL) and diethyl azodicarboxylate (0.18 mL). The mixture is stirred at room temperature overnight then concentrated under reduced pressure. The crude product is purified by flash column chromatography eluting with 2% to 6% methanol in dichloromethane and then by recrystallization from ethanolcyclohexane to afford 0.21 gm of the title compound as a white solid.
