実験手順

To a solution of 200 mg (0.55 mmol) 2-chloro-N-[(3-fluorophenyl)-methyl]-4-methyl-6-morpholin-4-yl-pyridine-3-carboxylic acid amide (synthesis is described in section a) of example 9) in THF (5 ml) were added 30 mg (0.055 mmol) Ni(dppp)Cl2 and 330 μl (0.66 mmol, 2M in THF) ethylmagnesiumbromide. The RM was heated to 80° C. for 8 h, followed by quenching with a sat. aq. NH4Cl sol. and extraction with EtOAc (3×20 ml). The combined organic layers were washed with water and brine, dried over Na2SO4 and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 7:3) provided 50 mg (0.14 mmol, 25%) Ethyl-N-[(3-fluorophenyl)-methyl]-4-methyl-6-morpholin-4-yl-pyridine-3-carboxylic acid amide (example 22). [M+H]+ 358.2.
