실험 절차
10.25 g of ethyl beta-methylaminocinnamate, 9.4 g of technical grade diketene and 25 ml dry methylene chloride are mixed in a flask fitted with a calcium chloride drying tube. The reaction mixture is stored at room temperature for 117 hours. Approximately 75 ml of dry ether is added and the resulting crystalline solid is filtered to yield 8.5 g of ethyl 1,6-dimethyl-2-phenyl-4-oxonicotinate. mp (toluene)=244°-248° C.
