실험 절차

To a 1 M solution of lithium aluminum hydride in tetrahydrofuran (0.60 mL, 0.59 mmol) is added a solution of 3-[4-(2-pyridin-2-yl-5,6-dihydro-4H-pyrrolo[1,2-b]pyrazol-3-yl)-quinolin-7-yloxymethyl]-pyrrolidine-1-carboxylic acid benzyl ester (215 mg, 0.39 mmol) in tetrahydrofuran (2 mL). The mixture is heated at 65° C. for 2 h, cooled to 0° C., and diluted with saturated aqueous sodium potassium tartrate solution. The mixture is extracted with chloroform and the organic portion chromatographed on SiO2 to yield the title compound, 112 mg (67%), as a yellow foam.
