Procedure

173 mg (1.25 mmol) of potassium carbonate are added to a solution of 171 mg (0.50 mmol) of tert-butyl 3-(3-trimethylsilylpropynoyl)pyrrolo[3,2-c]pyridine-1-carboxylate and 265 mg (1.25 mmol) of 2-methylphenylguanidinium nitrate (prepared by the method of J. L. Hughes et al., J. Med. Chem. 1975, 18, 1077-1088) in 2.5 ml of ethylene glycol monomethyl ether, and the mixture is heated at the boil for 18 hours. After cooling, the reaction mixture is partitioned between water and dichloromethane. The organic phase is dried over sodium sulfate and evaporated. The residue is chromatographed on a silica-gel column with dichloromethane/methanol as eluent, giving [4-(1H-pyrrolo-[3,2-c]pyridin-3-yl)pyrimidin-2-yl]-o-tolyl-amine (“A6”) as beige crystals; ESI 303;
