실험 절차

A mixture of 1 g of 2,2-dimethyl-4-(1-benzyl-1,2-dihydro-2-oxo-3-pyridyl)-6-cyano-3-chromanol and 10 ml of 85 percent phosphoric acid is warmed to 100° for 2 hours. After cooling and working up in the customary manner, there is obtained 2,2-dimethyl-4- (1-benzyl-1,2-dihydro-2-oxo-3-pyridyl)-6-carbamoyl -3-chromanol, m.p. 230°-235°.
