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

Participants

Reaction Steps

The same operation as in Example (42a) was performed using benzyl cis(±)-[3-methoxypiperidin-4-yl]carbamate hydrochloride obtained in Example (160a) (165 mg, 0.55 mmol), methyl 5-bromo-2-fluorobenzoate (128 mg, 0.55 mmol), palladium acetate (12.3 mg, 0.05 mmol), BINAP (68.3 mg, 0.11 mmol) and cesium carbonate (536 mg, 1.65 mmol), to obtain 33 mg of the title compound as a yellow oily substance (14%).
