tert-butyl N-[(4-bromofuran-2-yl)methyl]carbamate

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Under a nitrogen atmosphere, a solution of tert-butyl[(4-bromo-2-furyl)methyl]carbamate (15.3 g, 55.4 mmol) in dichloromethane (86 mL) at 0° C. was treated with trifluoroacetic acid (43 mL) over 15 minutes. The reaction mixture warmed to room temperature over 30 minutes. The solvent was removed in vacuo and chased with toluene (3×50 mL). The product was lyophilized for 18 hours to give the desired product as a brown solid (13.0 g, 81%). LCMS calculated for C5 BrO (M−NH2)+: m/z=158.9, 160.9. 1H NMR (400 MHz, DMSO-d6): δ 8.34 (br s, 3H), 8.01 (s, 1H), 6.70 (s, 1H), 4.08 (s, 1H). The solvent was removed in vacuo and chased with toluene (3×50 mL)
