經濟部中央標準局員工消費合作社印装 A7 B7 五、發明説明(1 ) 本發明涉及氰基亞胺基-1,3-D塞唑烷的新的製備方法。 已知,如果將N-氰基二硫代碳酸二甲酯與半胱胺在乙醇 中加熱回流,可以得到氰基爻胺基-1, 3-b塞唑垸(參見 Archiv der Pharmazie 305,731 (1972))。但是,該方 法的缺點是要消去2當量的甲基硫醇。由於甲基硫醇是一 種嚴重的呼吸系統毒物,必需有附加的安全措施,而且必 須將其焚毁或者通過用次氣酸鈉水溶液或過氧化氫氧化將 其破壤,因此由於毒理學和環境方面的原因,用這種途徑 進行工業化生產是非常昂貴的。 又已知,如果將N-氰基亞胺碳酸二甲酯與半胱胺在氫氧 化納水溶液中、於pH 10-11長時間挽拌,可以得到氰基亞 胺基-1,3-ϋ塞唑垸(參見Org. Prep.
