Procedure
Hydrogen was passed through a mixture of 25 g of ethyl 5-(n-propyl-5-thiazolyl)-2,4-pentadienoate, 250 ml of ethanol and 12.5 g of activated carbon containing 10% palladium with stirring for 2 hours and the mixture was filtered and the filter was washed with ethanol. The filtrate was evaporated to dryness under reduced pressure to obtain 23 g of raw ethyl 2-propyl-5-thiazole-pentanoate.
