  • Patent number: 11332495
    Abstract: Methods for preparing degarelix acetate are provided that include the steps of providing a suitable resin; deprotecting the resin with a diethylenetriamine solution; reacting sequentially the deprotected resin with different Fmoc protected amino acids; deprotecting the amino acid in each sequence with a diethylenetriamine solution in a stepwise fashion to yield a degarelix crude compound; and purifying the degarelix crude compound to yield pharmaceutically acceptable degarelix acetate. Methods of preparing degarelix acetate-mannitol premix and the resulting degarelix acetate-mannitol premix are also provided.

  • Publication number: 20170260157
    Abstract: Processes are disclosed for making pomalidomide which involve reducing 2-(2,6-dioxopiperidin-3-yl)-4-nitroisoindoline-1,3-dione using a catalyst and at least one solvent. The process may include reacting 3-nitrophthalic anhydride with ?-amino glutarimide hydrochloride to obtain the 2-(2,6-dioxopiperidin-3-yl)-4-nitroisoindoline-1,3-dione. The process may further include, prior to the reducing step, subjecting the 2-(2,6-dioxopiperidin-3-yl)-4-nitroisoindoline-1,3-dione to a purification process comprising heating a mixture of 2-(2,6-dioxopiperidin-3-yl)-4-nitroisoindoline-1,3-dione and 1,4-dioxane to obtain a solution, treating the obtained solution with carbon, removing the carbon from the solution to obtain a purified 2-(2,6-dioxopiperidin-3-yl)-4-nitroisoindoline-1,3-dione solution and using the purified 2-(2,6-dioxopiperidin-3-yl)-4-nitroisoindoline-1,3-dione solution for the reducing step.
