Participants

Procedure

1.00 g of (E)-4-[2-{2-[N-(4-methoxybenzenesulfonyl)amino]phenyl}ethenyl]pyridine was suspended in 40 ml of chloroform and, after adding 1.82 g of phenyl chlorocarbonate, 1.20 g of triethylamine was slowly added under ice cooling. Then, the mixture was stirred at room temperature for 5 minutes. The solvent was distilled off under reduced pressure and the desired product was purified by silica gel column (carrier: Wako Gel C200, developing solvent chloroform) to obtain the desired compound. The desired compound was treated with ethanol to obtain 0.71 g of a white granular crystal.
