A. Linden et al., 5-NITROPYRIMIDINES FROM 3,3-DIAMINO(2-NITRO)THIOACRYLAMIDES. STRUCTURE OF LAMINO)-2-(2-FURYL)-4-METHYLTHIO-5-NITROPYRIMIDINE, Acta crystallographica. Section C, Crystal structure communications, 50, 1994, pp. 421-424
The single-crystal X-ray structure determination of the product obtain
ed from the methylation of urfurylamino)-N-(2-furoyl)(2-nitro)thioacry
lamide, C-14-H12N4O4S, shows that the 4-methylthio-substituted 5-nitro
pyrimidine derivative was obtained, not the 1-methyl-4-thioxo-substitu
ted derivative as previously reported.
