Reaktionsschritte

The same operation as in Example (244b) was performed using methyl 5-bromo-3-methylthiophene-2-carboxylate obtained in Example (245a) (218 mg, 0.93 mmol), benzyl cis(±)-(3-methoxypiperidin-4-yl)-carbamate obtained in Example (40b) (270 mg, 1.02 mmol), palladium acetate (42 mg, 0.19 mmol), BINAP (115 mg, 0.19 mmol) and cesium carbonate (423 mg, 1.30 mmol), to obtain 92 mg of the title compound as a yellow oily substance (24%).
