Crystalline forms of 1S-[1alpha(2S*,3R*), 9ALPHA]-6, 10-dioxo-N(2-ethoxy-5-oxo-tetrahydro-3-furanyl) -9-[[(1-isoquinolyl) carbonyl]-amino] octahydro-6H-piridazino[1,2-A][1,2] diazepin- 1-carboxamide

摘要

A crystalline form of anhydrous 1S-[1alpha(2S*,3R*), 9ALPHA]-6, 10-dioxo-N(2-ethoxy-5-oxo-tetrahydro-3-furanyl)-9-[[(1-isoquinolyl) carbonyl]-amino] octahydro-6H-piridazino[1,2-A][1,2] diazepin-1-carboxamide which doesn't have the drawbacks of the currently known amorphous form of said compound; and a process for its preparation.
