Hydrochloric Acid → HCID 53716635, compound

Participants

Reaction Steps

A 50 mL round bottom flask equipped with a magnetic stirrer and a nitrogen inlet-outlet was charged with 4-(N,N-diphenylamino)cinnamic acid (1.0 g, 3.2 mmol) in 15 mL dichloromethane. Thionyl chloride (0.35 mL, 4.8 mmol) was added followed by 12.4 □L N,N-dimethylformamide. Hydrogen chloride gas evolution began immediately and then ceased within one hour of stirring. The solution was stirred for 3 h and then concentrated on a rotary evaporator. The product was transferred to a high vacuum line and residual solvent was removed under vacuum. The product was obtained as a brown solid and stored under nitrogen without any further purification.
