Reaction Steps

The title compound was prepared from 3-(4-methoxyphenyl)-8-methyl-8-azabicyclo[3.2.1]octan-3-ol (2 g, 8 mmol), glacial acetic acid (6.4 mL) and concentrated hydrochloric acid (6.4 mL). The free base of the title compound was dissolved in ethanol (96%) and added fumaric acid (0.8 g, 6.9 mmol), no precipitate appeared, the solution was concentrated to dryness, the residue was crystallised from absolute ethanol. Yield 1.1 g (40%) as white crystals m.p. 167.3-168.7° C.
