Procedure

A mixture of 5.0 gm (0.0356 mole) of 2-acetyl-6-methyl-2,3-dihydropyran, 3.64 gm (0.0356 mole) of n-butyric acid hydrazide and 100 ml of ethanol is refluxed 24 hr. The mixture is diluted with water to the cloud point and chilled. The product is collected, washed with water and dried to give 0.93 gm (12%) of the title compound having a melting point of 72.8° C.
