76003-29-7, 1-Boc-3-Oxopiperazine is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a solution of /er/-butyl 3-oxopiperazine-l-carboxylate (cas: 76003-29-7, 2 g, 10 mmol) in DMF (20 mL) that had been pre-cooled in an ice-water bath was added NaH (800 mg, 2.0 equiv.) in portions under N2. The mixture was stirred for 0.5 hours. (2- bromoethoxy)(ter/-butyl)dimethylsilane (cas: 86864-60-0, 5.3 mL, 2.5 equiv.) was added to the solution at 0 C. The reaction mixture was stirred at 25 C for 12 hours. The reaction mixture was then diluted with water (50 mL) and extracted with EtOAc (3 x 80 mL). The combined organic extracts was then washed with water (50 mL), brine (50 mL), and dried over Na2S04, then concentrated under reduced pressure to a residue. The residue was purified by silica gel chromatography to afford ketopiperazine 1-321 as a pale oil (1.8 g, 50% yield, pale oil). MS (ESI, pos. ion) m/z: 381 (M+23, 76003-29-7
As the paragraph descriping shows that 76003-29-7 is playing an increasingly important role.
