As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 7287-81-2, name is 1-(m-Tolyl)ethanol, molecular formula is C9H12O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. HPLC of Formula: C9H12O
General procedure: To a 20-mL tube equipped with a magnetic stirring bar was added acetophenone 1a (120 mg, 1 mmol), 2 mL of DMSO, iodine (25 mg, 0.1 mmol) and Fe(NO3)3·9H2O (40 mg, 0.1 mmol). Then the tube was sealed after being charged with oxygen to replace the air in it. The tube was placed into a preheated oil bath (130C), and the reaction solution was stirred for 12h. Then the reaction was quenched with water, and the pH of the aqueous phase was adjusted to 11 with 0.1 mol/L NaOH. After being washed with ethyl acetate (3 x 3 mL), the pH of the aqueous phase was adjusted to 2 with 0.1mol/L HCl and extracted with ether (3 x 6 mL). The combined ether phase was dried over anhydrous sodium sulfate and concentrated on a rotary evaporator to obtain the crude product. The crude product was purified by column chromatography on silica gel using ethyl acetate/petroleum ether as eluent to afford 2a as a white solid (104 mg, 85% yield). 1H NMR(600 MHz, DMSO-d6) delta 12.88 (s, 1H), 7.95 (d, J = 7.9 Hz, 2H), 7.62-7.59 (m, 1H), 7.50-7.48 (m, 2H); 13C NMR (125MHz, DMSO-d6) delta 167.3, 132.7, 130.8, 129.2, 128.5.
With the rapid development of chemical substances, we look forward to future research findings about 7287-81-2.
