実験手順

To a solution of rac-6-chloro-3-(3-chloro-benzyl)-3-piperidin-3-yl-1,3-dihydro-indol-2-one (80 mg, 0.20 mmol) (from Example 25a supra) in tetrahydrofuran (3 mL) was added triethylamine (32 mg, 0.3 mmol) (Aldrich), followed by the addition of 1-pyrrolidinecarbonyl chloride (34 mg, 0.24 mmol) (Aldrich). The mixture was stirred at 50° C. for 1 hour, then cooled to room temperature. The mixture was partitioned between ethyl acetate and water. The aqueous layer was extracted with another two portions of ethyl acetate. The combined organic layers were washed with water, brine, dried over Na2SO4 and concentrated. The residue were triturated with dichloromethane-hexanes to give rac-6-chloro-3-(3-chloro-benzyl)-3-[1-(pyrrolidine-1-carbonyl)-piperidin-3-yl]-1,3-dihydro-indol-2-one as a white solid. (Yield 50 mg, 50%).
