Versuchsvorschrift

A cooled (0° C.) solution of 6-((cyclopropylmethyl)(propyl)amino)pyrimidine-4-carboxylic acid (Intermediate 21, 0.23 g; 0.98 mmol) in DCM (5 ml) was treated with DMF (1 drop of a 10% solution in DCM) followed by (COCl)2 (0.1 ml; 1.15 mmol). After stirring at 0° C. for 30 minutes, the mixture was treated with 1H-indol-4-amine (Aldrich, 146 mg; 1.1 mmol) and diisopropylamine (0.5 ml; 2.9 mmol). After stirring overnight, water was added and the layers separated. The organic phase was passed through a hydrophobic frit and the solvent removed in vacuo. The residue was purified by column chromatography (silica) eluting with petroleum ether containing increasing amounts of Et2O to give the title compound as an off-white solid.
