실험 절차

Using General Method A, benzo[d]isoxazol-3-amine (500 mg, 3.37 mmol) and Troc-Cl (1.185 g, 5.59 mmol) were combined, purified by column chromatography (ethyl acetate/hexanes), triturated with hexanes (30 mL), filtered and dried to afford 2,2,2-trichloroethyl benzo[d]isoxazol-3-ylcarbamate. 1H NMR (300 MHz, DMSO-d6): δ 5.15 (s, 2 H), 7.50 (t, 1 H), 7.77-7.83 (m, 2 H), 8.16 (d, 1 H), 11.51 (s, 1 H); MS (ESI) m/z: 310.9 (M+H+).

후처리

  1. custompurified by column chromatography (ethyl acetate/hexanes)
  2. customtriturated with hexanes (30 mL)
  3. filtrationfiltered
  4. customdried
