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, 0.053 mmol) prepared in Example 1f, EDCl (20 mg, 0.1 mmol), HOBt (16 mg, 0.1 mmol) and DIPEA (40 mg, 0.3 mmol) in THF (1 mL) was added hydroxylamine hydrochloride ((18 mg, 0.26 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).
