実験手順

A mixture of tert-butyl 3-azabicyclo[3.2.1]oct-8-yl(methyl)carbamate (Preparation D; 2.60 g, 10.9 mmol), 4-(4-cyanophenyl)-4-(3,4-dimethoxyphenoxy)butyl methanesulfonate (see step (iii) above; 4.40 g, 10.9 mmol), and potassium carbonate (1.50 g, 10.9 mmol) in DMF (50 mL) was heated at 90° C. under nitrogen for 4 h. The mixture was partitioned with water (50 mL) and diethyl ether (50 mL). The aqueous layer was extracted with diethyl ether (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 3.60 g (60%) of the sub-title compound as an amorphous solid.
