英文摘要：

Starting from 4-chloropyridine, the target molecules, 4-chloro-2,6-diacetylpyridine and 4-chloro-2,6.dipropionylpyridine were synthesized through the radical acylation with a yield of 25.7% and 51.7%, respectively. The one-step synthetic method for the target molecule was a simpler way with higher yield comparing with the reported method.
