    Abstract: PROBLEM TO BE SOLVED: To provide a single-step, one-pot process to obtain zotarolimus and other rapamycin derivatives on large scale.SOLUTION: Dried rapamycin is dissolved in isopropylacetate. After cooling and 2,6-lutidine addition, triflic anhydride is slowly added at -30°C. Salts are removed by filtration. Tetrazole, followed by a tert-base diisopropylethylamine is added. After incubation at room temperature, the product is concentrated and purified by a silica gel column using THF/heptane as an eluant. The product is collected, concentrated, and purified using an acetone/heptane column. The product-containing fractions are concentrated. The product is dissolved in t-BME and precipitated with heptane. The solids are dissolved in acetone and treated with butylated-hydroxy toluene, and the solution is concentrated. The process is repeated twice with acetone to remove solvents. At least one stabilizing agent is added, such as BHT at 0.5% before drying.

    Abstract: PROBLEM TO BE SOLVED: To provide a one-pot synthesizing process to obtain zotarolimus and other rapamycin derivatives on large scale.SOLUTION: A dried rapamycin is dissolved in isopropyl acetate. The solution is cooled, and 2,6-Lutidine is added, followed by slowly adding trifluoromethanesulfonic anhydride at -30°C. Salts are then removed by filtration. Tetrazole, followed by a tert-base diisopropylethylamine is added. After incubation at room temperature, the product is concentrated and purified by a silica gel column using THF/heptane as eluant. The fractions containing the product are collected, concentrated, and purified again using an acetone/heptane column. The product containing fractions are concentrated. The product is dissolved in t-BME and precipitated with heptane. The solids are dissolved in acetone, treated with butylated-hydroxy toluene (BHT), and the solution concentrated. The process is repeated twice with acetone to remove solvents. At least one stabilizing agent is added, such as BHT at 0.5% before drying.
