Acetic Acid → HCID 70031142, compound

Participants

Reaction Steps

A solution of 402 mg (2.0 mmol) of methyl 3-amino-2,6-difluorophenylacetate (prepared in step 3 of example 24) in 15 mL of MeOH was treated with 1.1 mL (20.0 mmol) of HOAc and 0.28 mL (2.6 mmol) of 2-vinylpyridine. The reaction mixture was stirred at reflux for 16 h. The mixture was cooled and the acetic acid was removed in vacuo. The residue was dissolved in EtOAc and washed with saturated NaHCO3 (4×5 mL), water (1×10 mL) and brine. Column chromatography (1:4 EtOAc/Hex) afforded methyl 3-(2-pyridylethyl)amino-2,6-difluorophenylacetate.
