合成路线1
该中间体在本合成路线中的序号:(I)The Grignard condensation of 2,3-dichloroiodobenzene (I) with CO2 by means of Mg / ether gives 2,3-dichlorobenzoic acid (II), which is converted to the corresponding acyl chloride (III) by refluxing with SOCl2.The reaction of (III) with cuprous cyanide and KI in refluxing xylene yields 2,3-dichlorobenzoyl cyanide (IV). Finally, this compound is cyclized with aminoguanidine (V) in DMSO.
