Cesium carbonate → Methyl cis(+/-)-5-(4-{[(benzyloxy)carbonyl]amino}-3-methoxypiperidin-1-yl)-2-methoxybenzoate

Participants

Reaction Steps

The same operation as in Example (42a) was performed using methyl 5-iodo-2-methoxybenzoate (442 mg, 1.51 mmol), benzyl cis(±)-(3-methoxypiperidin-4-yl)-carbamate obtained in Example (40b) (400 mg, 1.51 mmol), palladium acetate (34 mg, 0.15 mmol), (±)-BINAP (188 mg, 0.30 mmol), cesium carbonate (1.08 g, 3.33 mmol), 1,4-dioxane (15 mL) and DMF (4.5 mL), to obtain 35 mg of the title compound as a yellow oily substance (5%).
