実験手順

A mixture of 3-benzyl-N-methyl-3-azabicyclo[3.2.1]octan-8-amine (Preparation B; 4.0 g, 17.4 mmol), 3-(4-cyanoanilino)propyl 4-methyl-benzenesulfonate (Preparation G(ii); 5.74 g, 17.4 mmol), and potassium carbonate (2.40 g, 17.4 mmol) in DMF (85 mL) was heated at 90° C. under nitrogen overnight. The mixture was partitioned with water (200 mL) and diethyl ether (150 mL). The aqueous layer was extracted with ethyl acetate (2×50 mL). The combined organic extracts were washed with brine (2×30 mL), dried (Na2SO4), filtered and then concentrated in vacuo. The residue was chromatographed on silica gel, eluting with dichloromethane:methanol (98:2), to afford 3.40 g (50%) of the sub-title compound as a white solid.
