Abstract
2-Amino-5-methyl-4-(2,2,2-trichloroethyl)-3-furonitrile was synthesized from 3,5,5,5-tetrachloropentan-2-one, a product of the radical addition of CCl4 to methyl vinyl ketone, according to a scheme known for α-haloketones. The product was converted via the corresponding imino-ether into N2-substituted N1 [5-methyl-4-(2,2,2-trichloroethyl)-3-cyano-2-furyl]formamidines. Cyclization of these formamidines gave 2-methyl-3-(2,2,2-trichloroethyl)-5-R-4-imino-4,5-dihydrofuro[2,3-d]pyrimidines, which readily regroup according to Dimroth into 2-methyl-3-(2,2,2-trichloroethyl)-4-R-aminofuro[2,3-d]pyrimidines.
