実験手順

The present invention also provides another method for preparing the crystalline Form I, comprising: (a) heating 10-30% by weight of (R)-7-chloro-N-(quinuclidin-3-yl)benzo[b]thiophene-2-carboxamide hydrochloride in acetonitrile or an aqueous acetonitrile to between 60° C. and the boiling point of the solution, (b) optionally adding water to the mixture to fully dissolve the (R)-7-chloro-N-(quinuclidin-3-yl)benzo[b]thiophene-2-carboxamide hydrochloride; (c) cooling the solution until crystals are just visible; (d) if the water content is greater than 3% volume/volume when crystals are just visible, adding acetonitrile to the mixture so that the water content is less than 3% volume/volume; (e) cooling the resulting mixture to below 15° C.; and (f) isolating crystalline (R)-7-chloro-N-(quinuclidin-3-yl)benzo[b]thiophene-2-carboxamide hydrochloride monohydrate.
