专利号:US-4266058-A 优先权日:1979-07-04 标 题:Synthesis of 2-isopropylamino-pyrimidine 发明人:DEMOSTHENE CLAUDE G; ASPISI CHRISTIAN R 权利人:SOC D ETUDES PROD CHIMIQUE 摘要:The present invention provides a process for the synthesis of 2-isopropylamino-pyrimidine by aminolysis of 2-methylsulphonyl-pyrimidine using isopropylamine. The aminolysis is effected, according to the present invention, by refluxing isopropylamine and 2-methylsulphonyl-pyrimidine in the absence of a solvent. Using this technique, the 2-isopropylamino-pyrimidine has been obtained in a substantially quantitative yield.
专利号:US-9550000-B2 优先权日:2011-09-09 标题 :Compositions, methods, and systems for the synthesis and use of imaging agents 发明人:ROBINSON SIMON P; YU MING 权利人:ROBINSON SIMON P; YU MING; LANTHEUS MEDICAL IMAGING INC 摘要:The present invention relates to systems, compositions, and methods for the synthesis and use of imaging agents, or precursors thereof. An imaging agent precursor may be converted to an imaging agent using the methods described herein. In some cases, the imaging agent is enriched in 18 F. In some cases, an imaging agent may be used to image an area of interest in a subject, including, but not limited to, the heart, cardiovascular system, cardiac vessels, brain, and other organs. In some embodiments, methods and compositions for assessing perfusion and innervation mismatch in a portion of a subject are provided.
