PIPERAZINE-2-CARBOXYLIC ACID Chemical Properties,Uses,Production
Application
Piperazine-2-carboxylic acid dihydrochloride can be used as a pharmaceutical synthesis intermediate. The reaction proceeds as follows: Piperazine-2-carboxylic acid dihydrochloride (2 g, 9.8 mmol) and (Boc)?O (8.6 g, 39.4 mmol) are dissolved in THF (40 mL) and water (40 mL). Sodium bicarbonate (8.31 g, 79.8 mmol) is added. The reaction mixture is magnetically stirred at room temperature for 4 hours, then ethyl acetate is added. The mixture is separated using a separatory funnel. The separated organic phase is washed with saturated brine, dried over anhydrous sodium sulfate, concentrated under reduced pressure, and then separated by silica gel column chromatography. 2.5 g of 1,4-di-tert-butoxycarbonylpiperazine-2-carboxylic acid (13-2) was obtained after purification, with a yield of 78%. LC-MS (ESI): m/z (M+1) 331.2.
