실험 절차

To a solution of tert-butyl 3-azabicyclo[3.2.1]oct-8-yl(methyl)carbamate (Preparation D; 1.68 g, 7.0 mmol) in dichloromethane (35 mL) at 25° C. under nitrogen was added trimethylaluminum (3.75 mL of 2.0 M in hexanes, 7.0 mmol). After stirring at 25° C. for 30 min, 4-(2-oxiranyl-methoxy)benzonitrile (Preparation E(i); 1.22 g, 7.0 mmol) was added in one portion, and the mixture was stirred overnight. The mixture was quenched with 3 N NaOH (11.5 mL) and stirred for 1 h. Water (30 mL) was added, and the aqueous layer was extracted with dichloromethane (3×30 mL). The combined organic extracts were dried (Na2SO4), filtered and concentrated in vacuo to afford an oil. The residue was chromatographed on silica gel, eluting with dichloromethane:methanol (98:2), to afford 2.35 g (81%) of the subtitle compound as a white solid.
