実験手順

A mixture of (S)-methyl 1-(2-(quinuclidin-3-ylamino)ethyl)-1H-benzo[d]imidazole-7-carboxylate (0.2 g, 0.7 mmol) from Step F above, lithium hydroxide monohydrate (0.1 g, 2.1 mmol), water (5 mL), and tetrahydrofuran (5 mL) was heated at reflux for 5 h. The reaction solution was cooled to room temperature and concentrated under reduced pressure to give lithium (S)-1-(2-(quinuclidin-3-ylamino)ethyl)-1H-benzo[d]imidazole-7-carboxylate (0.2 g): MS (ESI+) m/z 315 (M+H).
