Acetyl chloride → 2-Propanone, 1-(4,5-dihydro-2-oxazolyl)-

참여 물질

반응 단계

To a solution of 8.5 g. (0.1 mole) of 2-methyl-1,3-oxazoline in 85 ml. of dry tetrahydrofuran, and cooled in an acetone-dry ice bath to -60° C., is added 6.4 g. (0.1 mole) of n-butyl lithium and the reaction mixture allowed to stir for 1 hour. To the cloudy solution is then added 7.8 g. (0.1 mole) of acetyl chloride at such a rate that the temperature is maintained below -50° C. The reaction mixture is allowed to warm to room temperature and is then filtered and the solvent removed in vacuo. The desired product is purified by distillation under reduced pressure.
