A solution of trans-4-(4-methylbenzothiazol-2-yl)-2-methylpiperidine (0.061 g, 0.248 mmol, prepared in example 24) and (S)-(+)-4-(oxiranylmethoxy)benzo[b]furan (0.047 g, 0.248 mmol) in methanol (3 mL) was heated at reflux for 18 hours and then cooled and evaporated. The residue was purified using silica gel chromatography (dichloromethane/2% methanol/0.2% ammonium hydroxide in dichloromethane gradient elution) to give the free bases of the title compounds as two separate yellow oils. The oxalate salts were prepared to give the title compounds.
