Reaction Steps

1 g (10.4 mmol) of 4H-pyran-4-on was dissolved in 10 ml of pyridine, 3.38 g (25 mmol) of 2,2,2-trifluoroethylamine hydrochloride was added, and reacted at 70° C. for an hour. The solvent was removed, and the residue was purified by chloroform-methanol (10:1) silica gel chromatograph to obtain 1.7 g of the title compound.
