Paragraph 0037; 0038, (2017/02/28)
The invention discloses a copper bromide reagent, a preparation method thereof, and a synthesis method of alpha-amido propiophenone and derivative thereof. Copper bromide cheap in industry and 2,6-bi[4-(1,1-dimethyl)-2-oxazoline-2-base] pyridine react to directly obtain high yield of high-purity copper bromide reagent, in addition, the copper bromide reagent and propiophenone containing multiple important functional groups have good reaction activity. Due to the characteristic, high yield of alpha-amido propiophenone and derivative thereof can be obtained in mild conditions, conventional expensive azoic compound materials are not used, the cost is lowered to a large extent, the operation requirement is also lowered, and alpha-amido propiophenone and derivative thereof have good application prospect in industry.
