A mixture of 3.3 g (0.027 mole) of 3-ethylcyclobutanecarboxylic acid (prepared in 1E) and 9.4 g (5.7 ml, 0.080 mole) of thionyl chloride was prepared and allowed to stir at room temperature for about 15 hr. Excess thionyl chloride was removed by distillation at atmospheric pressure. The residue was distilled at reduced pressure to yield 2.4 g of the title compound having the following physical characteristics:
