Reaction Steps

1.4 g of 5-bromo-6-ethyl-4-hydroxy-3-propionyl-pyrone (a melting point of 76.5° C to 77.5° C) was dissolved in 10 c.c. of ethanol and further 0.5 g of ethoxyamine was added in it and the resulting solution was agitated at room temperature during 4 hours. Further, it was agitated at a temperature of 40°-50° C during 30 minutes. Then, above ethanol was distilled off from the resulting reaction mixture under a reduced pressure and thereby, a crude white crystal was obtained. Further, the crude white crystal was recrystallized by using n-hexane and thus, a white spicular crystal was obtained as an objective compound.
