合成路线图解说明: The condensation of 2,4-bis(1-pyrrolidinyl)-6-(1-piperazinyl)pyrimidine (I) with 3-(bromomethyl)-5-chlorobenzonitrile (II) gives the disubstituted piperazine derivative (III). The partial hydrolysis of the CN group of (III) with methanol/HCl yiedls the iminoether (IV), which is condensed with 4-pyridylcarbonylhydrazide (V) to afford the amidrazone (VI). Finally, this compound is cyclized by heating. |
