Application
DPAT: Usable Acid Catalyst for the Ester Synthesis
Experimental procedure: 3-Phenylpropionic acid (150 mg, 1.0 mmol), 1-octanol (130 mg, 1.0 mmol), and DPAT (3.2 mg, 0.01 mmol) are heated (80 °C) in toluene for 4 h. Evaporation of toluene under reduced pressure gives the crude material, which is purified by column chromatography (hexane:ether=10:1) to give the desired carboxylic ester (244 mg, 93%).
