Versuchsvorschrift

2,6-Dichlorophenyl isocyanate (0.075 g) was added to a mixture of 4-aminothieno[3,2-d]pyrimidine (Tetrahedron, 1971, 27, 487; 0.201 g) and acetonitrile (16 ml) and the resultant mixture was stirred at ambient temperature for 16 hours. The precipitate was isolated and washed in turn with diethyl ether and methanol. There was thus obtained the title compound (0.31 g); NMR Spectrum: (DMSOd6) 7.25 (t, 1H), 7.45 (d, 1H), 7.55 (d, 1H), 7.95 (d, 1H), 8.4 (s, 1H), 8.8 (s, 1H), 11.7 (br s, 1H); Mass Spectrum: M+H+ 339 and 341; Elemental Analysis: Found C, 45.8; H 2.4; N, 16.5; C13H8Cl2N4OS requires C, 46.03; H, 2.38; N, 16.52%.
