150407-69-5, (S)-1-((Benzyloxy)carbonyl)-4-(tert-butoxycarbonyl)piperazine-2-carboxylic acid is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
150407-69-5, A mixture of (S)- 1 -((benzyloxy)carbonyl)-4-(tert-butoxycarbonyl)piperazine- 2- carboxylic acid (500 mg, 1.372 mmol, 1.0 eq), 6-chloro-pyridin-2-ylamine (265 mg, 2.058 mmol, 1.5 eq), and EDCI (790 mg, 4.116 mmol, 3.0 eq) in pyridine (25 mL) was stirred at r.t. for 6 h. The reaction was monitored by LC-MS and TLC. The mixture was concentrated and the resulting residue was purified by chromatography on silica gel column (PE/EA = 5/1, v/v) to give the crude (S)- 1-b enzyl 4-tert-butyl 2-((6-chloropyridin-2-yl)carbamoyl)piperazine- 1,4-dicarboxylate (400 mg, 61%) as a white solid.
As the paragraph descriping shows that 150407-69-5 is playing an increasingly important role.
