Introduction | 2-amino-5-iodopyrimidine is a cream to brown crystalline powder with a density of 2.204g/cm3, boiling Point: 364.9°C at 760 mmHg, Melting Point: 219°C, Flash point: 174.5°C. |
Use | 2-amino-5-iodopyrimidine is a pharmaceutical intermediate. |
preparation | 2-amino-5-iodopyrimidine can be prepared from 2-aminopyrimidine, prepared after iodination. It has been reported in the literature to be useful in the preparation of CDK4/6 inhibitors. Add 2-aminopyrimidine (2.4g, 25 mmol, 1.0 equiv) and iodine (2.7g, 10.7 mmol, 0.43 equiv) to 60 ml of glacial acetic acid, additional periodic acid (0.86G, 3.76 mmol, 0.15 equiv) and a solution of 0.5 of concentrated sulfuric acid in 3 ml of water were then added. The reaction system was heated to 80 degrees under nitrogen for 24 hours. The reaction solution was then poured into saturated aqueous sodium thiosulfate solution until the solution was clear and extracted with dichloromethane (200 ml× 3). The mixed organic phase was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure, 2-amino-5-iodopyrimidine (1.4g, 22.2% yield) was obtained as a white solid after silica gel column chromatography.
