Procedure

The same operation as in Example (160b) was performed using benzyl cis(±)-[3-methoxypiperidin-4-yl]carbamate hydrochloride obtained in Example (160a) (832 mg, 2.76 mmol), ethyl 5-bromopyridine-3-carboxylate (530 mg, 2.3 mmol), palladium acetate (51.72 mg, 0.23 mmol), BINAP (286.89 mg, 0.46 mmol), and cesium carbonate (2.25 g, 6.91 mmol), to obtain 487 mg of the title compound as a yellow oily substance.
