Procedure

Ethyl 1-aminocyclohexancarboxylate hydrogen chloride (5.800 g), triethylamine (13.62 mL) and 1-bromo-2-(2-bromoethoxy)ethane (4.21 mL) were stirred together in N,N-dimethylformamide (50 mL) at 95° C. overnight. The reaction mixture was diluted with ethyl acetate (150 mL), washed with water (100 mL) and brine (100 mL), dried over magnesium sulfate, filtered, and concentrated. Silica gel chromatography eluting with a gradient of 5% to 25% ethyl acetate/hexanes provided the title compound.
