Procedure

4-[4-(2-Pyridin-2-yl-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazol-3-yl)-quinolin-7-yl]-benzoic acid (Example 41 before reverse phase chromatography, 0.08 g, 0.185 mmol), (2-aminoethyl)-carbamic acid tert-butyl ester (0.036 g, 0.2 mmol), N—N-Diisopropylethylamine (0.08 mL, 0.46 mmol) and HBTU (0.076 g, 0.2 mmol) are mixed in 10 mL of DMF and stirred at RT for 8 h under nitrogen. The crude mixture is diluted with EtOAc (30 mL) and extracted with saturated NaHCO3. The organic phase is separated and washed with saturated brine, dried (Na2SO4), filtered, evaporated to a solid mass. The crude product is purified by MPLC on silica gel (80% EtOAc/Hexanes, 1% MeOH) to yield the title compound, 0.059 g (56%), as white solid.
