| | 3-METHOXY-N-METHYLBENZYLAMINE 97 Usage And Synthesis |
| Chemical Properties | Liquid | | Uses | 3-Methoxy-N-methylbenzylamine is used as an intermediate in the synthesis of diclofensine hydrochloride. | | Synthesis | To a solution of 3-methoxybenzaldehyde (180 g, 1.32 mol) in methanol (1 L) was slowly added 40% aqueous methylamine (113 mL, 1.31 mol), and the reaction mixture was stirred at 0 °C for 1 hour. Subsequently, sodium borohydride (75 g, 1.98 mol) was added in batches at the same temperature and stirring was continued for 1 hour. Upon completion of the reaction, the solution was concentrated under reduced pressure to a smaller volume, diluted with water (200 mL) and extracted with dichloromethane (3 x 500 mL). The organic phases were combined, dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give the crude product N-methyl-3-methoxybenzylamine (220 g, quantitatively) as a clear oil, which was used directly in the subsequent reaction without further purification.1H NMR (CDCl3, 500 MHz) δ: 7.23 (t, J = 8.0 Hz, 1H), 6.92-6.88 (m, 2H), 6.81-6.78 (m, 2H), 6.81-6.78 (m, 2H), 6.81-6.78 (m, 2H). 6.81-6.78 (m, 1H), 3.80 (s, 3H), 3.73 (s, 2H), 2.45 (s, 3H), 2.07 (br s, 1H). | | References | [1] Patent: WO2010/132437, 2010, A1.
