実験手順
A reaction mixture of 2-(5-amino-7-bromo-3-chloro-5H-chromeno[2,3-c]pyridin-5-yl)ethanol (2.8 g, 7.87 mmol) and 4-nitrobenzoyl isothiocyanate (1.639 g, 7.87 mmol) in THF (100 mL) was stirred at RT for 1 hour. The reaction mixture was then concentrated under reduced pressure to afford N-(7-bromo-3-chloro-5-(2-hydroxyethyl)-5H-chromeno[2,3-c]pyridin-5-ylcarbamothioyl)-4-nitrobenzamide (5 g, 8.87 mmol).
