4-Nitrobenzoic Acid → HCID 70237031, compound

Participants

Reaction Steps

0.4 mmol of 1,4-diazabicyclo[2.2.2]octane and then 0.78 mmol of para-nitrobenzoic acid are added to a solution of 0.6 mmol of the compound obtained in Step 1 in 10 ml of anhydrous dichloromethane. After 7 hours at ambient temperature, the reaction mixture is evaporated and the residue is chromatographed. The isolated product is then dissolved in 50 ml of methanol and Dowex 50X2-200 resin is added. After stirring for 15 hours at ambient temperature, the reaction mixture is filtered and then concentrated under reduced pressure, enabling the expected product to be isolated.
