Versuchsvorschrift

To a solution of 3-{4-[2-(6-methyl-pyridin-2-yl)-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazol-3-yl]-quinolin-7-yl}-propionic acid methyl ester (0.30 g, 0.73 mmol) and 2M dimethylamine in methanol (1.05 mL, 2.1 mmol) in dichloromethane (1 mL) is added 2 M trimethylaluminum in hexane (1.64 mL, 3.25 mmol). The solution is heated at 40° C. for 48 h. The mixture is diluted with dichloromethane (150 mL), treated with saturated potassium sodium tartrate (30 mL), and stirred 18 h. The organic portion is separated and; washed with water and brine, dried (sodium sulfate), filtered, and concentrated in vacuo. The residue is chromatographed on SiO2 (10% methanol in dichloromethane) to yield the title compound, 0.29 g (89%), as a yellow foam.
