26%; 5% | With sodium hydrogencarbonate; In acetonitrile; at 90℃; for 48h;Inert atmosphere; | General procedure: A Kimax tube was charged with an equimolar quantity of benzoic acid 33-37 (1.3mmol, 1 equiv.), sodium bicarbonate (1.3mmol, 1 equiv), and the dibromoalkane (1.3mmol, 1 equiv.) in anhydrous acetonitrile or DMF (10mL). The tube was flushed with argon, stopped, and the reaction mixture was stirred at 65C or 90C for the time indicated in each case. The solvent was evaporated under vacuum to give a crude solid residue. The different products were isolated by silica chromatography (5g SI prepacked column) using hexane/EtOAc (100/0→50/50) as eluent. The structure of the obtained isomer (i.e. the benzoate product and not the 4-alkyloxy-substituted benzoic acid isomer) was checked by 1H-13C HMBC and NOESY experiments. |
