Vorschrift

To a mixture of 8.2 mg of 7-methyl-4-oxo-1-(tetrahydro-2H-pyran-4-yl)-4,5-dihydro-1H-pyrazolo[4,3-c]quinoline-8-carboxylic acid, 3.8 mg of 1-(2-aminoethyl)piperidine, 13.1 μL of DIPEA, and 0.4 mL of DMF was added a mixture of 9.8 mg of HATU and 0.1 mL of DMF, followed by stirring at room temperature overnight. The reaction mixture was purified by preparative HPLC (methanol/0.1% aqueous formic acid solution) to obtain 3.6 mg of 7-methyl-4-oxo-N-[2-(piperidin-1-yl)ethyl]-1-(tetrahydro-2H-pyran-4-yl)-4,5-dihydro-1H-pyrazolo[4,3-c]quinoline-8-carboxamide.
