Abstract

Experimental Ethyl 3-Thieny1acetate.-A mixture of 56 nil. of coiicd. sulfuric acid dissolved in 186 ml. of absolute ethanol and 112 g.(0.91 mole) of 3-thienylacetonitrile6 was refluxed for seven hours, cooled, and poured into 200 ml. of water. After washing and drying the oily layer which separated, it was distilled through a short Vigreux column, and 89.5 g.(627,) of a colorless oil boiling from 107-115 at 6 mm.\ vx obtained.
