실험 절차

To a 10 mL round-bottomed flask, 6-(3-(piperazin-1-yl)propoxy)-3-(3,5-difluorophenyl)-2-(pyridin-3-yl)-1H-inden-1-one (40 mg, 0.09 mmol) obtained in Step 1 of Example 66 and CH2Cl2 (2 mL, 0.05M) were charged. Pyridine (0.01 mL, 1.2 eq) was added and then the mixture was cooled to 0° C. and treated with acetic anhydride (0.01 mL, 1.2 eq). After being stirred for 15 h, the mixture was diluted with CH2Cl2 and washed with H2O and brine. The organic layer was dried over MgSO4 and concentrated in vacuo. The residue was purified by being purified by silica gel column chromatography (CH2Cl2/MeOH=9:1) and being purified by prep. HPLC (20% H2O/CH3CN) to provide the title compound (25.9 mg, 59%).
