実験手順
400 mg (1.70 mmol) of 7,8-dihydro-6,6-dimethyl-7-hydroxy-8-amino-6H-pyrano[2,3-f]benzo-2,1,3-oxadiazole and 40 ml of dichloromethane were stirred at room temperature, and 192 μl (1.87 mmol) of 3-chloropropyl isocyanate were added thereto and stirred for 5 hours. The crystals precipitated were taken out by filtration to obtain 250 mg of the intended compound as pale yellow crystals. (yield: 41%)
