Procedure
After 1g of 3-(1-ethoxyaminopropylidene)-6-ethyl-3,4-dihydro-2H-pyrane-2,4-dione was dissolved in 50ml of acetone containing 5% of water, it was irradiated with high-pressure mercury arc for a day. Chloroform was added to the residue after the distillation of acetone and the insoluble crystal was obtained by filtration of chloroform solution containing the residue. The crude product was recrystallized from the mixture of benzene and petroleum ether, and thereby 0.6g of 3-(1-ethoxyamino-1-hydroxypropyl)-6-ethyl-3,4-dihydro-2H-pyrane-2,4-dione having a melting point of 63° to 64°C as a white plate was obtained.
