ethyl-2,2-dimethyl-7-bromoheptanoate Chemische Eigenschaften,Einsatz,Produktion Methoden

Beschreibung
Ethyl 7-bromo-2,2-dimethylheptanoate is an important raw material in the synthesis route of bepetidic acid. Bempedoic acid, whose chemical name is 8-hydroxy-2,2,14,14-tetramethylpentadecanedioic acid, also known as ETC-1002, is a new type of lipid developed by the American EsperionTherapeutic company Quality regulation small molecule drugs. As one of the company's main drug candidates, its targets are liver adenosine triphosphate-citrate lyase (ACL) and adenosine monophosphate-activated protein kinase (AMPK).
Verwenden
Ethyl-2,2-dimethyl-7-bromoheptanoate can be used as an intermediate in organic synthesis, mainly used in laboratory research and development and chemical production processes.
Synthese

The specific embodiment of the present invention is as follows: prepare 19.4g (167mmol) of ethyl isobutyrate in 216mL solution of tetrahydrofuran with a mass concentration of 10%, connect to metering pump 1; prepare 84mL (168mmol) of 2.0M n-butyllithium solution, connect to meter Pump 2; configure 1,5-dibromopentane 80.0g (348mmol) tetrahydrofuran 100mL solution, mass concentration is 63%, connected to metering pump 3.Configure 300mL of 1N hydrochloric acid solution and connect to metering pump 4.Set continuous flow precooler 1, the circulating temperature is 0, and reach stability; set continuous flow precooler 2, the circulating temperature is 0, and reach stability; set continuous flow precooler 3, and the circulating temperature is 0, and reach stability; set continuous flow precooler 4, cycle temperature is 0, and reach stability;Set the flow rate of metering pump 1 to 65.0ml/min, set the flow rate of metering pump 2 to 25.0ml/min, set the flow rate of metering pump 3 to 30.0ml/min, and set the flow rate of metering pump 4 to 90.0ml/min.Turn on the metering pump 1 and metering pump 2 at the same time. After 60s of operation, turn on the metering pump 3, and after 60s of operation, turn on the metering pump 4 to collect the outflowing reaction liquid in the storage tank.After the operation is completed, separate the liquids, collect the upper organic phase, concentrate under reduced pressure at P=-0.08MPa, T=45??C to remove low-boiling solvents, and then rectify under reduced pressure at P=5mmHg and T=70??C to obtain 38.4 g.The obtained product is a colorless liquid with a GC purity of 98.6% and a yield of 87%.
