Procedure

A mixture of 30.3 g (0.3 mole) triethylamine, 18.3 g. (0.1 mole) zinc acetate, 55.0 g. (0.206 mole) 5-phenyl-2-trichloromethyloxazolidine and 15.6 g (0.206 mole) carbon disulfide was stirred at ambient temperatures for 17 hours and then was heated at 50°C, for three hours. A reddish amber-colored semi-solid was obtained after the volatile materials were distilled off at 50°/25 mm. Hg. The semi-solid was dissolved in methanol and the resulting solution added to water with vigorous stirring. the solids were filtered, air-dried, and redissolved in benzene. After drying the solution with magnesium sulfate, filtering the mixture and evaporating the solvent, 37 g. (58%) of the desired product (m.p. 91°-93°C.) was obtained; its infrared spectrum was consistent with the structure.
