Abstract

The invention relates to a crystal form of an intestinal type 2B sodium phosphate cotransporter (Npt2b) inhibitor and a preparation method thereof. Specifically, the present invention relates to N 1 ‑Methyl‑N 1 ‑(2‑morpholinoethyl)‑N 3 ‑(3‑(4‑phenethylphenylcarbamoyl)‑4,5,6,7‑tetrahydrobenzo[b]thiophen‑2‑yl)isophthalamide sulfate (formula (I) Compound) II crystal form and preparation method. The crystal form II of the compound of formula (I) obtained in the present invention has good chemical stability and crystal form stability, and can be better used in clinical treatment.

Description

technical field [0001] The present invention relates to N 1 -Methyl-N 1 -(2-morpholine ethyl)-N 3 -(3-(4-phenylethylphenylcarbamoyl)-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)II crystal form of isophthalamide sulfate and Preparation. Background technique [0002] Inorganic phosphate (Pi) is an essential component of bone mineral. About 80% of human phosphate is in the extracellular matrix (such as bone and tooth) in vitro, 18% is in the cell, and 2% is in the extracellular fluid. Under normal physiological conditions, excess phosphate is taken up by the small intestine, and phosphate homeostasis is regulated by the excretion and reabsorption of the kidneys. Too much or too little phosphate in the body will lead to dysfunction of the body and cause disease: if it is too low, it will cause hypophosphatemia, rickets, and cardiac dysfunction; if it is too high, it will induce hyperphosphatemia, soft tissue and Vascular calcification and renal dysfunction. Excessive phosphate...
