196811-66-2, tert-Butyl 4-carbamothioylpiperazine-1-carboxylate is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
To a stirred solution of tert-butyl 4-carbamothioylpiperazine-1-carboxylate (synthesized according to Example 5, Step 1, 1.31 g, 5.36 mmol) in isopropanol (15 mL), tert-butyl 3-bromo-2,4- dioxopiperidine-1-carboxylate obtained in the first step (1 .3 g, 4.46 mmol) was added at rt. The reaction mixture was stirred overnight at 90 C. It was cooled down to rt and evaporated under reduced pressure. Water (10 mL) was added and the desired product was extracted with diethyl ether (2 x 30 mL), dried over Na2SO4 and concentrated, affording the title product. Yield: 74% (1.42 g, yellow solid). LCMS: (Method A) 239.0 (M-Boc+H), Rt. 0.70 min, 48.39% (Max)., 196811-66-2
As the paragraph descriping shows that 196811-66-2 is playing an increasingly important role.
