Participants

Reaction Steps

A mixture of 100 mg (0.36 m mol) of 7,8-dihydro-6,6-dimethyl-7-hydroxy-8-acetylamino-6H-pyrano [2,3-f] benzo-2,1,3-oxadiazole, 2 ml of pyridine and 34 μl (0.36 m mol) of acetic anhydride was stirred at the room temperature for 24 hours. After the completion of the reaction, the mixture was diluted with ethyl acetate, washed with water and saturated anhydrous NaCl solution and dried over anhydrous magnesium sulfate. After the solvent was distilled off, the residue was recrystallized from chloroform to obtain 58 mg (yield: 26%) of the intended compound.
