To a stirred solution of (4-(4-chlorophenoxy)piperidin-1-yl)(1H-indol-5-yl)methanone (80 mg, 0.23 mmol, Step-1 of Example 353) and sodium hydride (60% in oil, 27 mg, 1.13 mmol) in N,N-dimethylformamide (5 mL) was added tert-butyl (2-bromoethyl)carbamate (76 mg, 0.34 mmol) at room temperature. Then the mixture was stirred at 70° C. for 3 hours. The mixture was poured into water (30 mL) and extracted with ethyl acetate (30 mL). The organic layer was washed with water (30 mL), and dried over sodium sulfate. After removal of the solvent, the residue was purified by silica-gel column chromatography (eluting with n-hexane/ethyl acetate=2/1) to give 112 mg (>99% yield) of the title compound as brown oil.
