Crystalline | [Uses]
L-Glutamic acid dimethyl ester hydrochloride is used as a pharmaceutical intermediate. | [Uses]
L-Glutamic Acid Dimethyl Ester is a diester analogue of L-Glutamic Acid, a non-essential amino acid. L-Glutamic Acid Dimethyl Ester has been shown to antagonize the effects of morphine sulfate. | [reaction suitability]
reaction type: solution phase peptide synthesis | [Synthesis]
To a 500 mL four-necked flask equipped with a stirrer, thermometer and reflux condenser (connected to a 30% aqueous sodium hydroxide solution absorption unit), 300 g of methanol, 14.7 g (0.10 mol) of L-glutamic acid, and 30.0 g (0.25 mol) of thionyl chloride were added sequentially. The reaction mixture was heated to 60-63 °C and the reaction was stirred at this temperature for 7 hours. Upon completion of the reaction, the system was cooled to 20-25 °C, followed by the passage of nitrogen to displace the hydrogen chloride gas in the system for 30 min. Next, the excess thionyl chloride and methanol were recovered by distillation. To the residue, 100 g of methyl tert-butyl ether was added and pulped, followed by filtration to collect the solid. Upon drying, 20.8 g of L-glutamic acid dimethyl ester hydrochloride was obtained as a white solid. The product was analyzed by high performance liquid chromatography (HPLC) with 99.5% purity and 98.1% yield. | [References]
