Procedure

To a solution of (S)-methyl 1-(phenylsulfonyl)-3-(2-(quinuclidin-3-ylamino)ethyl)-1H-indole-4-carboxylate (480 mg, 1.02 mmol) from Step D above in tetrahydrofuran (10 mL) was added lithium hydroxide monohydrate (129 mg, 3.07 mmol) in water (3 mL). The mixture was stirred at ambient temperature overnight and then concentrated under reduced pressure. The residue was dried overnight under vacuum to afford crude lithium (S)-1-(phenylsulfonyl)-3-(2-(quinuclidin-3-ylamino)ethyl)-1H-indole-4-carboxylate, which was used in the next step without further purification: MS (ESI+) m/z 454 (M+H).
