Hazard Class | IRRITANT |
use | 2-aminothiophene-3-nitrile is a pharmaceutical intermediate. Due to its important role in immunity, HPK1 inhibitors play an important role in malignant solid tumors or hematological cancers (such as acute myeloid leukemia, bladder epithelial cancer, breast cancer, colon cancer, lung cancer, pancreatic cancer, melanoma), autoimmune diseases (Such as systemic lupus erythematosus, psoriatic arthritis) and inflammatory response. |
Preparation | 2-aminothiophene-3-nitrile is a pharmaceutical intermediate, which can be made of 1, 4-dithiane-2, 5-Diol and malononitrile are prepared by one-step reaction. There are reports that it can be used to prepare HPK1 inhibitors. The raw materials 1,4-dithiane -2,5-diol (100g,0.66mol,1.0eq) were dissolved in methanol (500mL), then malononitrile (86.86g,1.32mol,2.0eq) and triethylamine (20mL) were added, the reaction was carried out at 70 ℃ for 30 minutes, TLC detection was complete, the reaction solution was concentrated, and the crude product was carried out by silica gel column chromatography (PE:EA = 4:1) purified yellow solid product (80g, yield: 98%). |
