摘要：A process for preparing a 2,3-trans-1,4-bridged cyclohexane sulfonamide derivative of Formula (I): wherein R is phenyl or phenyl substituted with hydroxy, lower alkoxy, halogen or lower alkyl; Y is unsubstituted or substituted methylene, ethylene, vinylene or oxygen; m is 0 or 1; n is 0, 1 or 2 with the proviso that when m is 0, n is not 0, and when m is 1, n is not 2, in which a cis/trans mixture of 1,4-bridged cyclohexane sulfonamides of Formula (I) min : wherein R, Y, m and n are as defined above, in a mixture of water and an organic solvent at pH 3 - 7, is reacted with an anionoid reagent or a water-soluble carbonyl reagent to form a water-soluble adduct only with the trans isomer of said sulfonamide (I), and in which the resulting compound of Formula (I) is separated in the form of said water-soluble adduct with said anionoid reagent or water-soluble carbonyl reagent.
