Participants

Reaction Steps

2-(3-Methyl-2,3-dihydro-6-benzofuryloxy)-5-aminopyridine (0.5 g) was dissolved in 2.5 ml of pyridine, and a solution of composed 0.27 g of dimethylcarbamoyl chloride and 2.5 ml of toluene was added. A solution composed of 0.27 g of diethylcarbamoyl chloride and 2.5 ml of toluene was added, and the mixture was stirred at room temperature for 9 hours. Water and ethyl acetate were added to the reaction mixture, and the organic layer was separated. The organic layer was washed with a saturated aqueous solution of sodium chloride, and dried over anhydrous magnesium sulfate. Ethyl acetate was evaporated under reduced pressure, and the precipitated crystals were washed with n-hexane to give 0.63 g (yield 96%) of the desired product as pale brown crystals.
