Reaction Steps

To a mixture of 200 mg (0.850 m mol) of 7,8-dihydro-6,6-dimethyl-7-hydroxy-8-amino-6H-pyrano [2,3-f] benzo-2,1,3-oxadiazole and 20 ml of dichloromethane were added 92 μl (0.935 m mol) of isopropyl isocyanate with stirring at the room temperature, followed by stirring for 6 hours. The precipitated crystals were filtered off to obtain 120 mg (yield: 44%) of the intended compounds as colorless crystals.
