tert-Butyl carbazate → HCID 90036206, compound

Participants

Reaction Steps

To a stirred suspension of 2-methoxyquinoline-3-carboxylic acid (0.92 g, 4.55 eq) in DCM (45 mL) under N2, HOBT (6.83 mmol, 1.5 eq), EDC.HCl (6.83 mmol, 1.5 eq) triethylamine (5.0 mmol, 1.1 eq) and tert-butylhydrazine carboxylate (5.00 mmol, 1.1 eq) were added. The mixture was stirred at room temperature for 3 h, diluted with DCM and washed with sat. aq. NaHCO3 and sat. aq. NaCl. The organic phase was dried (Na2SO4), concentrated under reduced pressure and the product was purified by flash chromatography (SiO2, Petroleum ether/EtOAc 9:1 to 0:100) affording 1.23 g of product as a white solid (85% yield). MS (ES) C16H19N3O4 requires: 317.34, found: 318.
