7664-66-6, name is 4-Isopropoxyaniline, belongs to ethers-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. HPLC of Formula: C9H13NO
To a solution of 4-isopropoxyaniline (9.06 g, 60.0 mmol) in CH2Cl2 (120 mL) and pyridine (30 mL) was added 4-nitrophenyl chloroformate (10.9 g, 54.0 mmol) portionwise with stirring over ~1 min with brief ice-bath cooling. After stirring at room temperature for 1 h, the homogeneous solution was diluted with CH2Cl2 (300 mL) and washed with 0.6 M HCl (1*750 mL) and 0.025 M HCl (1*1 L). The organic layer was dried (Na2SO4) and concentrated to give the title compound as a light violet-white solid (16.64 g, 98%). 1H NMR (CDCl3) delta 8.31-8.25 (m, 2H), 7.42-7.32 (m, 4H), 7.25-7.20 (m, 2H), 6.93 (br s, 1H), 2.90 (sep, J=6.9 Hz, 1H), 1.24 (d, J=6.9 Hz, 6H). LC/MS (ESI) calcd for C16H17N2O5 (MH)+ 317.1, found 633.2 (2 MH)+.
The synthetic route of 7664-66-6 has been constantly updated, and we look forward to future research findings.
