Versuchsvorschrift

The present invention further includes a method for preparing the crystalline Form II, the method comprising: (a) adding (R)-7-chloro-N-(quinuclidin-3-yl)benzo[b]thiophene-2-carboxamide hydrochloride to (i) acetonitrile or (ii) aqueous acetonitrile to create a composition that is 10-20% by weight of (R)-7-chloro-N-(quinuclidin-3-yl)benzo[b]thiophene-2-carboxamide hydrochloride; (b) optionally adding water to the composition to make the water content 6-10%; (c) optionally cooling the solution at below 10° C.; (d) allowing crystals to form; and (e) isolating crystalline (R)-7-chloro-N-(quinuclidin-3-yl)benzo[b]thiophene-2-carboxamide hydrochloride monohydrate.
