Use | 2-amino-5-fluoropyrimidine can be used as a synthetic intermediate in pharmaceutical and chemical industry. |
preparation | the preparation of 2-amino-5-fluoropyrimidine is as follows: 2-chloro-5-fluoropyrimidine (280 μL, 2.264mmol) and ammonia (5ml,68mmol) in methanol (860 μL) the mixture was heated to 110 °c for 30 min through a microwave reactor. The reaction was filtered and the solid was washed with MeOH. The solid was dried to give 5-fluoro-2-pyrimidinamine (247mg,2.184mmol,96% yield) as a white crystalline solid. |
