Reaction Steps

To a stirred solution of (R)-methyl 1-(2-(quinuclidin-3-ylamino)ethyl)-1H-indole-7-carboxylate (1.6 g, 5.0 mmol) from Step C above in THF (20 ml) and H2O (20 ml) was added lithium hydroxide monohydrate (632 mg, 15.1 mmol). The mixture was stirred at room temperature overnight and then concentrated under reduced pressure. The residue was dried overnight under vacuum to afford crude lithium (R)-1-(2-(quinuclidin-3-ylamino)ethyl)-1H-indole-7-carboxylate which was used in the next step without further purification: MS (ESI+) m/z 314 (M+H).
