実験手順

To the solution of 2-fluoro-3-Hydroxy-benzamide (0.12 g, 0.774 mmol) in 20 mL DMF 1-bromohexane (0.13 mL, 1.0 mmol), Potassium Carbonate (0.213, 1.4 mmol) was added. The reaction mixture was stirred at 90° C. for 4 h. DMF was distilled off and the reaction mixture was extracted with EtOAc. The obtained crude compound was purified by column chromatography on silica (230-400μ) using ethyl acetate/hexane (50:50) as the eluent to provide the title compound. (0.05 g, 28%). 1H NMR (DMSO-d6, 400 MHz with D2O): δ 0.82-0.99 (m, 3H), 1.10-1.33 (m, 6H), 1.67-1.71 (m, 2H), 3.99-4.15 (t, 2H, J=8.0 Hz), 7.08-7.24 (m, 2H). MS ES+ (214.33), HPLC (method 6) Rt=11.15 min.
