Procedure

The title compound was prepared by the Suzuki coupling procedure of Example 7, step (d) using 3-(4-amino-3-bromo-phenyl)-propionamide (as prepared in Example 7, step (c), 76.0 mg, 0.351 mmol), and 4,4-dimethylcyclohexen-1-yl boronic acid (59.5 mg, 0.387 mmol). Silica gel chromatography (0-2% MeOH/DCM) afforded the title compound (79 mg, 92%) as a light brown oil. Mass spectrum (ESI, m/z): Calcd. for C17H24N2O, 273.2 (M+H). found 273.2.
