Versuchsvorschrift

A cooled (0° C.) solution of 6-(cyclohexyl(cyclopropylmethyl)amino)pyrimidine-4-carboxylic acid (Intermediate 13, 130 mg; 0.47 mmol) in DCM was treated with diisopropylamine (90 mL; 0.52 mmol) and methyl chloroformate (40 mL; 0.52 mmol). After stirring at 0° C. for 15 minutes, ethyl 4-(4-aminophenylsulfonyl)butanoate (Intermediate 48, 130 mg; 0.48 mmol) was added. After stirring at 0° C. for 30 minutes and RT for 1 hour, saturated sodium bicarbonate solution was added and the mixture stirred for 15 minutes. DCM was added and the layers separated. The organic extract was filtered 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 EtOAc to give the title compound as a white solid.
