  • Stable solid forms of regadenoson
    Patent number: 10144756
    Abstract: A process for the preparation of the amorphous form of Regadenoson of formula is disclosed together with new crystalline polymorphic forms E, F and G and methods for their preparation. Regadenoson amorphous form can be prepared in mild reaction conditions with high chemical purity (>99.6%) and high stability to the heating. A particularly thermodynamically stable anhydrous crystalline form of Regadenoson (form G) is also disclosed, provided with high stability not when exposed to 90% RH at 25° C. for 96 hour, but also to the heating up to 200° C.
    Type: Grant
