tert-butyl N-[2-(3-fluorophenyl)-2-oxoethyl]carbamate

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

実験手順: To a flask were added tert-butyl[2-(3-fluorophenyl)-2-oxoethyl]carbamate (0.32 g, 1.3 mmol) and ammonium acetate (2.02 g, 26.2 mmol) and methanol (10 mL) and sodium cyanoborohydride (0.22 g, 3.5 mmol). The mixture was refluxed for 2 h. The solvent was removed under vacuum. To the residue was added EtOAc and 50 mL of 1M NaOH. The aqueous phase was extracted again with fresh EtOAc. The combined organic extracts were dried over sodium sulfate, filtered and dried under vacuum to give 0.301 g (94% yield) of the final product as oil. LC-MS found: 155.1 (M−Boc)+. The mixture was refluxed for 2 h The solvent was removed under vacuum To the residue was added EtOAc and 50 mL of 1M NaOH The aqueous phase was extracted again with fresh EtOAc The combined organic extracts were dried over sodium sulfate filtered dried under vacuum
