Reaction Conditions

Reaction Steps

A mixture of 2-benzyloxy-6-fluoroaniline (950 mg, 4.37 mmol), methyl bromoacetate (456 μL, 737 mg, 4.82 mmol), and potassium carbonate (1.21 g, 8.76 mmols) in DMF (10 mL) is heated at 60° C. for 18 h. The mixture is poured into ethyl acetate and extracted once with water and five times with brine. The organic layer is dried, filtered, and the solvent removed under reduced pressure to afford a crude oil that is chromatographed on an Isco Companion (80 g silica gel, 0-30% gradient of hexane/ethyl acetate) to afford methyl 2-(2-benzyloxy-6-fluoroanilino)-acetate as an oil. MS (M+1)+=290; NMR (CDCl3): δ 7.39 (m, 5H), 6.67 (m, 3H), 5.10 (s, 2H), 4.57 (br s, 1H), 4.11 (m, 2H), 3.72 (s, 3H).
