Participants

Reaction Steps

Racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-1′-fluorocarbonylmethyl-2′-(1-methylene-propyl)spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione (0.1 g, 0.21 mmol) prepared in example 107a was stirred in a methanolic ammonia solution (7N, 10 mL) at room temperature for 18 h. The reaction mixture was concentrated, and the residue was purified by chromatography (EtOAc:MeOH=10:1) to give racemic (2′R,3R,4′S)-6-chloro-4′-(3-chlorophenyl)-2′-(1-methylene-propyl)-1′-[aminocarbonyl-methyl]spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as a yellow solid (Yield 41 mg, 40%).
