Thionyl Chloride → HCID 14989579, compound

Participants

Reaction Steps

0.988 gm (3.0 mmol) of ethyl 6,7,8-trifluoro-1,4-dihydro-1-(1-hydroxyprop-2-yl)-4-oxoquinoline-3-carboxylate was dissolved into 50 ml of chloroform. To this was added 0.714 gm (6.0 mmol) of thionyl chloride and the mixture was reacted with heating under refluxing for 10 hours. The reaction mixture was concentrated under reduced pressure and the residue was purified by silica gel column chromatography (chloroform:methanol=100:1) to obtain 1.001 gm of colorless, needlelike crystals of ethyl 1-(1-chloroprop-2-yl)-6,7,8-trifluoro-1,4-dihydro-4-oxoquinoline-3-carboxylate.
