Versuchsvorschrift

Combine 1-(3,4,5-trimethoxybenzoyl)-3-(2-(4-(1-(2-methylsulfonylethyl)-1H-benzimidazol-2-yl-amino)piperidin-1-yl)ethyl)-3-(3,4-difluorophenyl) pyrrolidine (1.0 g, 1.38 mmol) and ethyl acetate (50 mL). Add methanesulfonic acid (0.27 g, 2.76 mmol). Heat to reflux. After 1 hour, cool to ambient temperature and stir. After 40 hours, add diethyl ether (150 mL) to give a solid. Repeatedly, decant the solvent add diethyl ether before collecting the solid and drying in vacuo to give the title compound.
