Reaction Steps

100 mg (0.38 mmol) N-Ethyl-2-(4-piperidin-4-yl-phenyl)-propionamide (VI.1) in 2 mL DMSO are added to a mixture of 99 mg (0.38 mmol) 1-bromo-4-cyclopropylmethoxy-2-methoxy-benzene, 106 mg (0.77 mmol) potassium carbonate, 7.3 mg (0.038 mmol) copper(I) iodide and 8.8 mg (0.077 mmol) (L)-proline under inert gas atmosphere. The mixture is stirred for 7 d at 90° C. and for additional 4 d at 100° C. After that time, the mixture is filtered and the solvent is evaporated. The residue is purified by HPLC (column: Waters XBridge 50; eluent A: water+0.3% NH4OH, eluent B: MeOH) to yield the desired product.
