실험 절차

To a 100-ml three-necked round flask (equipped with a stirrer tip, a Dimroth condenser, a thermometer and a trap of NaOH) were introduced 13.3 g (52.4 mmol) of 3-(2-biphenylyl)-2-ethylpropionic acid and 25.9 ml (355 mmol) of thionyl chloride, and they were refluxed for 2.5 hours with heating in a nitrogen atmosphere. After the reaction was completed, the unreacted thionyl chloride was distilled off under reduced pressure to obtain 15.2 g of a crude product as a yellow orange liquid. This acid chloride was used for the next reaction without further purification. The properties of the product thus obtained are described below.
