252990-05-9, Methyl (R)-1-Boc-piperazine-2-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

A mixture of Compound 13A (605 mg, 2.46 mmol), l-(/er/-butyl) 2-methyl (f?)-piperazine-l,2-dicarboxylate (500 mg, 2.05 mmol), and K2CO3 (424 mg, 3.07 mmol) in DMF (10 mL) was stirred at 60 C for 4 hours. The reaction mixture was diluted with water (50 mL) and extracted with ethyl acetate (50 mL x 2). The combined organic extracts were washed with brine (50 mL), dried over anhydrous sodium sulfate, filtered, and concentrated under reduced pressure. The residue was purified with flash column chromatography on silica gel (ethyl acetate in petroleum ether, 10% v/v) to yield Compound 13B-1: LC-MS (ESI) m/z: 411 [M+H]+.
