Procedure

At room temperature, a mixture of racemic (2′S,3S,4′R)-4′-[2-(2-amino-ethoxy)5-chloro-phenyl]-6-chloro-2′-(5-fluoro-2-methyl phenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (100 mg, 0.189 mmol) prepared in Example 32e, cyclobutanecarboxylic acid (98 mg, 0.948 mmol), EDC.HCl (181 mg, 0.948 mmol), HOBt (128 mg, 0.948 mmol) and DIPEA (245 mg, 1.897 mmol) in anhydrous DMF (4 mL) was stirred overnight. Then the mixture was filtered and the filtrate was concentrated. The residue was purified by Prep-HPLC to give the title compound as a white solid (19 mg).
