반응 단계

13.2 g of potassium hydroxide pellets (85 %) are heated to 45° C. in 27 g of thioglycerol. 10 ml of N-methylpyrrolidone are added followed portionwise over 30 minutes by 0.1 mole (23.2 g) of 2-hydroxy-5-nitrobenzyl bromide. The temperature of 67°-70° C. which is obtained is maintained for 30 minutes after the end of addition. The reaction mixture is diluted with 300 g of iced water. After neutralizing with acetic acid, the expected product precipitates. After filtering off, followed by drying at 45° C. under vacuum the product obtained is recrystallized from isopropyl acetate. It melts at 130° C.
