실험 절차

To a mixture of 5-(2-hydroxy-3-pyrrolidin-1-yl-propoxy)-6-methoxy-indan-1-one (Intermediate N) (0.16 g, 0.0005 mole), 3-methoxy-phenyl isothiocyanate (Compound 19a) (0.08 mL, 0.0006 mole) and THF (1.5 mL) was added to lithium hexamethyldisilane (0.7 mL, 0.0007 mole) dropwise at room temperature with stirring. The reaction mixture was stirred for 4 hrs. Hydrazine (0.035 mL, 0.0011 mole) and acetic acid (0.66 mL, 0.0011 mole) were added to the reaction mixture. The reaction mixture was then heated at the reflux temperature for 18 hrs. To the resulting mixture was first added water (10 mL) and then the reaction mixture was extracted with CH2Cl2. The organic layers were combined and washed with aqueous NaHCO3 solution, then washed with water and brine solution, dried (Na2SO4), and solvent was removed in vacuo. The crude material was purified by reverse phase HPLC. Lyophilization yielded the title compound, 1-[7-Methoxy-3-(3-methoxy-phenylamino)-2,4-dihydro-indeno[1,2-c]pyrazol-6-yloxy]-3-pyrrolidin-1-yl-propan-2-ol as a white powder.
