Reaction information

*#Reaction file  
*Reaction file type CDX

To a pre-dried sealed tube, with a screw down Young tap, methylamine (66 % solution in IMS, 27.2 mL, 544 mmol) was added followed by 4-bromo-1-butene (20.0 g, 136.0 mmol).  The tube was sealed, heated to 80 °C in an oil bath for 48 hours, the reaction mixture cooled to 0 °C, then quenched with a saturated solution of NaHCO3 (50.0 mL).  The product was extracted into diethyl ether (3 x 50 mL), washed with water (3 x 50 mL), brine (50.0 mL), dried over MgSO4, filtered and the solvent removed under reduced pressure.  The product was purified by distillation through a Dufton column at atmospheric pressure (B.p. 80-82 °C) to afford N-(3-butenyl)-N-methylamine (2.50 g, 29 mmol, 21 %) as a colourless oil.  N,N-di(3-butenyl)-N-methylamine (305) was isolated by distillation at atmospheric pressure (B.p. 120-122°C) as a colourless oil (4.8 g, 34 mmol, 51 %).
