実験手順

To a solution of 3-hydroxybenzenecarboxamide (200 mg, 1.46 mmol, 1 equiv.) in DMF (3 ml) was added K2CO3 (302 mg, 2.19 mmol, 1.5 equiv.) and NaI (43.5 mg, 0.29 mmol, 0.2 equiv). The suspension was stirred for 5 min before n-nonyl chloride (0.32 ml, 1.61 mmol, 1.1 equiv) was introduced. The resulting mixture was warmed to 60° C. where it was maintained for 16 h. After this time, the reaction was cooled to room temperature and partitioned between EtOAc and water. The organic phase was separated, washed with additional water (×2), dried (MgSO4), filtered and concentrated in vacuo to reveal a colourless solid. In the case of 3-n-nonyloxybenzamide this colourless solid was stirred for 5 min with MeOH (˜0.5 ml) [NB: 3-n-nonyloxybenzamide partially soluble in MeOH] and then filtered to reveal the desired compound as a colourless solid (116 mg, 30%). HPLC-MS (method 3): m/z 264 [M+H]+, Rt=1.80 min. 1H NMR (d6-DMSO) δ=7.95 (s, 1H), 7.44-7.31 (m, 4H), 7.06 (ddd, J=8 Hz, J=2 Hz, J=1 Hz, 1H), 3.99 (t, J=6.5 Hz, 2H), 1.72 (quintet, J=6.5 Hz, 2H), 1.42 (m, 2H), 1.34-1.26 (m, 10H), 0.86 (t, J=6.5 Hz, 3H).
