Dichloromethane → 4-(Trifluoromethyl)cinnamoyl chloride

Participants

Reaction Steps

To a 500 mL round-bottomed flask was added 4-(trifluoromethyl)-cinnamic acid (231 mL, 116 mmol), DCM (7.44 mL, 116 mmol), thionyl chloride (17.7 mL, 243 mmol), and a few drops of DMF. The resulting mixture was stirred at reflux for about 1.5 hours and followed by LCMS (MeOH quench). Once no starting material was present, the solvents were reduced and the oil was used immediately in the next step.
