実験手順: To 110 mg (0.5 mmol) of methyl 2,5-dichloro-3-aminobenzoate were added 190 mg (0.5 mmol) of HATU, 70 mg (0.5 mmol) of HOAt, 152 mg (0.5 mmol) of Boc-Glu-OtBu hydrochloride, 0.21 ml (1.5 mmol) of triethylamine and 2 ml of dichloromethane. The mixture was stirred at room temperature overnight.

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 2,5-Dichloro-3-aminobenzoic acid, 206 mg (1.0 mmol), was dissolved in 4 ml of acetone, and 0.7 ml (1.4 mmol) of 2.0 M trimethylsilyl diazomethane solution in hexane was added to the solution. The mixture was stirred at room temperature for 1.5 hours. The solvent was removed by distillation to give methyl 2,5-dichloro-3-aminobenzoate. The solvent was removed by distillation
