Reaction Steps
To a mixture of 1.1 g of 2-amino-3-hydroxypyridine VIII and 1.1 g of etyl acetoacetate is added 4 ml of polyphosphoric acid and the resultant mixture is stirred under heating at 100° C. for 4 hours. The reaction mixture is poured into ice water, and the resulting solution is adjusted to PH 4 with 2N aqueous sodium hydroxide, then to PH 7 with aqueous sodium carbonate and shaken with CHCl3. The organic layer is washed with water and dried over anhydrous sodium sulfate. The solvent is evaporated to give 0.9 g of the titled compound XV-1.
