Reaktionsschritte
The same operation as in Example (42a) was performed using benzyl cis(±)-[3-methoxypiperidin-4-yl]carbamate hydrochloride obtained in Example (160a) (190 mg, 0.63 mmol), methyl 5-chloro-2-methylpyridine-3-carboxylate (117 mg, 0.63 mmol), palladium acetate (14.2 mg, 0.06 mmol), BINAP (78.6 mg, 0.13 mmol) and cesium carbonate (617 mg, 1.89 mmol), to obtain 225 mg of the title compound as a brown oily substance (86%).
