Procedure

While cooling and stirring 250 g. of pyridine, 175 g. (1.40 moles) of thiazolidine hydrochloride [preparation described by S. Ratner and H. Clarke, J. Am. Chem. Soc. 59, 200 (1937)] was added. After it had dissolved, 106.4 g. (1.40 mole) of carbon disulfide was added dropwise, followed by 128.5 g. (0.70 mole) of anhydrous zinc acetate. The resulting reaction mixture was stirred at 40° - 50° C for 2 hours. The precipitate was filtered at 5° - 10° C. The crude solid was water-washed and finally freed of pyridine by vacuum-drying at 120° C to give 147.8 g. of the desired product. It gradually decomposed starting at ca. 200° C without a definite final decomposition point. A small sample washed with hot benzene had the following analysis: Found: C, 24.46; H, 2.95; N, 7.31; Zn, 16.58%. Calcd for C8H12N2S6Zn: C, 24.40; H, 3.05; N. 7.12; Zn, 16.62%.
