A mixture of 2,6-difluoro-3-hydroxybenzenecarboxamide (1.2 g, 7 mmol, 1 equiv.), K2CO3 (2.87 g, 21 mmol, 3 equiv.) and methyl bromoacetate (0.69 ml, 7.35 mmol, 1.05 equiv.) in DMF (30 ml) was stirred at r.t. for 18 h. The mixture was diluted with water and extracted with EtOAc (4×80 ml). The combined organic extracts were dried (MgSO4) and evaporated to dryness under reduced pressure. The product was used crude on the next step. HPLC-MS (method 1): m/z 246 [M+H]+, Rt=2.08 min.
