Propanedioic acid, 1-methyl ester, potassium salt (1:1) Use and Manufacturing
General procedure: According to the literature procedure, To the reaction flask was added 100 g of dimethyl malonate (0.757 mol) and 350.0 g of anhydrous methanol, and the mixture was completely mixed and dissolved, and a methanol solution of potassium hydroxide was slowly added dropwise at 10 to 35 ° C (potassium hydroxide: 42.3 G (0.754 mol), methanol: 350.0 g), Gradually there is a white solid precipitation process. After dripping, The reaction solution was further stirred at 10 to 35 ° C for about 3.5 hours.The temperature was raised to 65 to 68 ° C. The system was refluxed and filtered while hot to remove dipotassium malonate. The resulting filtrate was cooled to 0 ° C and filtered to give the monomethyl methyl malonate salt.After the filtrate was concentrated and further about 550 g of methanol was distilled off, the resulting concentrate was cooled to 0 ° C and filtered, and the resulting two partsPotassium monoglyceride potassium salt combined, vacuum drying, the final monomethyl methacrylate potassium salt 98.78g (HPLC purity:99.1percent yield: 82.80percent).Comparison To a water-cooled solution of dimethylmalonate (132 g, 1 mol) in MeOH (500 mL) was added KOH (56 g, 1 mol) portionwise. The reaction mixture was stirred for 16 h, the solid was filtered off, and the filtrate was condensed TO-100 mL. Ether was added to precipitate out the solid, which was filtered and washed with ether, then dried to yield a white solid (102 g, 65percent).
A protein advanced glycosylation inhibitor.
