In this paper, A was prepared/produced/synthesized from raw material a, b and c, at a yield of 91%. Subsequently, having a reaction with d and e to produce the key intermediate B, giving a yield of 70%. Lastly, it underwent an aromatic nucleophilic substitution reaction with c derivatives. Thus, synthesizing 3 target compounds, which has not been reported in any papers. The structure of the target compounds were characterized by IR,MS. Structure of the target compounds were as follows: |
