    • N-acetylcysteine, carboxymethylcysteine and thiazolidincarboxylic acid salts of erythromycin-2-propionate are produced by charging erythromycin-2-propionate and the sulphur-containing acid into a reactor. The reactants are homogenised and milled under nitrogen for 1 - 2 hours at 10 - 20 DEG C. To this mixture purified water is added under nitrogen and the resultant aqueous mixture is further homogenised and milled for 1 to 2 hours at 10 - 30 DEG C under nitrogen to produce a suspension of the desired salt. The suspension is dried under vacuum to produce a high yield of the desired salt at high levels of purity. Carboxymethylcysteine, N-acetylcysteine and thiazolidin-carboxylic acid salt of erythromycin, clarithromycin, roxithromycin and azithromycin may be produced in a similar manner.
    • 通过将红霉素-2-丙酸酯和含硫酸装入反应器中制备红霉素-2-丙酸的N-乙酰半胱氨酸,羧甲基半胱氨酸和噻唑烷羧酸盐。 将反应物均化并在10-20℃下在氮气下研磨1-2小时。向该混合物中加入纯化水,并将所得含水混合物进一步均化并在10-30℃下研磨1至2小时 在氮气下产生所需盐的悬浮液。 将悬浮液在真空下干燥以产生高纯度的所需盐的高产率。 红霉素,克拉霉素,罗红霉素和阿奇霉素的羧甲基半胱氨酸,N-乙酰半胱氨酸和噻唑烷 - 羧酸盐可以以类似的方式制备。
