実験手順
4-Biphenyl sulfonic acid (2.4 g, 10 mmol) was heated to 100° C. with phosphorus pentachloride (2.1 g, 10 mmol) overnight. The reaction was cooled to RT, diluted with water, filtered and washed with water. The solid was then triturated with EtOAc-ether and the beige solid was used in the next reaction without further purification.
