144 mg (0.50 mmol) of 6-aminocarbonyl-4-(3-chloroanilino)-7H-pyrrolo[2,3-d]pyrimidine and 202 mg (0.5 mmol) of Lawesson's reagent in 5 ml of THF are heated to boiling for 17 h and the mixture is then evaporated. Column chromatography (SiO2, CH2Cl2/ethanol=15:1) of the residue and stirring in diethyl ether yields 4-(3-chloroanilino)-6-(thiocarbamoyl)-7H-pyrrolo[2,3-d]pyrimidine; HPLC: tRet(Grad20)=9.8; TLC-Rf=0.44 (CH2Cl2/methanol=10:1); FAB-MS: (M+H)+=304; IR: (KBr) inter alia 1614s, 1566s, 1506m, 1474s, 1380m, 1354m, 1294m, 1134m.
