Abstract: Utilize pmethoxybenzaldehyde as a starting material, after oximationdehydration, crosscoupling, nucleophilic addition and oxidation closedloop fourstep reactions synthesized target product 3(4methoxyphenyl)4methyl5isothiazoleamine,and the total yield is up to 4715%.By optimizing the process conditions obtained the optimum dosage of hydroxylamine hydrochloride and thioacetamide.The structure of the target product was confirmed by GCMS and 1H NMR. The experimental results show that the reaction condition is mild, product yield is high, simple workup, less three wastes, and with good prospects for industrial applications.

Key words: pmethoxybenzaldehyde; menzonitrile; isothiazole; GluR1 antagonistL
