Title: Improvements in and relating to the manufacture of iodinated acyl taurines
IPC: C07C309/15
Filed: 1942-11-13
Abstract: Iodine substituted acyl taurines are prepared by treating an iodine substituted alkyl, aryl, aralkyl, or heterocyclic carboxylic halide with an N-substituted taurine.  Alternatively, the carboxylic acid halide may be first reacted with the taurine and then the acyl taurine treated with an iodinating agent such as iodine monochloride. The reactions are preferably carried out in the presence of an acid acceptor.  In examples: (1) 2 : 3 : 5-Tri-iodobenzoyl chloride is added to taurine in small amounts alternatively with caustic soda to give 2 : 3 : 5-triiodobenzoyl taurine.  (2) A dioxane solution of 3 : 4 : 5-tri-iodobenzoyl chloride is added to an aqueous-dioxane solution of taurine containing sodium hydroxide and sodium carbonate to give 3 : 4 : 5-tri-iodobenzoyl taurine.  (3) An acetone suspension of 4 - acetamino - 3 : 5 - di - iodobenzoyl chloride is added to an ice-cold caustic soda solution of taurine, as in Example 1, to give 4-acetylamino-3 : 5-di-iodobenzoyl taurine.  (4) An acetone solution of 3 : 5-di-iodo-4-acetoxy-benzoyl chloride is added to an aqueous-acetone solution of taurine containing sodium hydroxide and sodium carbonate, to give after treatment with barium chloride, the barium salt of 3 : 5-di-iodo-4-hydroxy-benzoyl taurine.  The sodium salt may be obtained from the barium salt by the addition of sodium sulphate.  Alternatively, 3 : 5-di-iodo-4-hydroxy benzoyl taurine may be made by first acylating taurine by treatment with 4-acetoxy benzoyl chloride in the presence of an acid acceptor followed by the addition of a slight excess of iodine dissolved in dilute sodium hydroxide, and hydrolysis of the acetoxy group.  (5) A dioxane solution of 2 : 4 : 6-tri-iodobenzoyl chloride is added to a solution of taurine in aqueous-dioxane containing sodium hydroxide and sodium carbonate to form 2 : 4 : 6-tri-iodo-benzoyl taurine.  (6) A dioxane solution of 3 : 5-di-iodo-benzoyl chloride is added to an alkaline aqueous solution of taurine to form 3 : 5-di-iodobenzoyl taurine. (7) 2 : 5-di-iodo-benzoyl taurine is formed from the corresponding 2 : 5-di-iodo compound in the same manner as example 6.  (8) A dioxane solution of 2-hydroxy-3 : 5-di-iodobenzoyl chloride is added to an alkaline aqueous-dioxane solution of taurine to give 2-hydroxy-3 : 5-di-iodobenzoyl taurine.  (9) An acetone-dioxane solution of 4-methoxy 3 : 5-di-iodobenzoyl chloride is added to an aqueous alkaline solution of taurine to form 4-methoxy-3 : 5-di-iodobenzoyl taurine.
