Procedure
To a mixture of racemic (2′S,3S,4′R)-6-chloro-4′-[5-chloro-2-(1-hydroxycarbonyl-1-methyl-ethoxy)-phenyl]-2′-(5-fluoro-2-methyl-phenyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (30 mg, 0.05 mmol) prepared in Example 1f, EDCl (20 mg, 0.1 mmol), HOBt (16 mg, 0.1 mmol) and DIPEA (20 mg, 0.15 mmol) in THF (1 mL) was added cyanamide (50% in H2O) (20 mg, 0.24 mmol). The mixture was stirred at room temperature overnight and purified by prep-HPLC to give the title compound as a white solid (14 mg).
