Autor: K. S. Avetisyan, L. Kh. Galstyan
Publikováno v: Russian Journal of Organic Chemistry. 55:974-977
The alkylation of 5,5-disubstituted N-[4-methyl-3-phenylfuran-2(5H)-ylidene]-N′-phenylthioureas with ethyl chloroacetate in the presence of potassium carbonate at a ratio of 1:1:0.6 led to the formation of the corresponding S-(ethoxycarbonylmethyl)
