実験手順
4-(4-Nitrobenzyl)-phenylmethanesulfonic acid sodium salt (2.29 g) was combined with phosphorus pentachloride (1.45 g). The mixture was heated to 90° C. for 5 minutes, poured into water, and extracted with dichloromethane (3x 20 mL). Solvents were evaporated to give 4-(4-chlorosulfonylmethylbenzyl)-nitrobenzene as an impure yellow solid (0.63 g). This product was used directly in the next step.
