Participants

Reaction Steps

To a solution of 150 mg (0.45 mmol) 2-ethylsulfanyl-N-[(3-fluorophenyl)-methyl]-6-(methyl-amino)-4-methyl-pyridine-3-carboxylic acid amide (synthesis is described in section a) of example 123) in DCM (3 ml) and THF (3 ml) was added 160 μl (0.95 mmol) DIPEA. At 0° C. 56 μl (0.47 mmol) 4-fluoro-benzoylchloride was added dropwise and stirring was continued at 0° C. for 2 h and RT for 16 h. Then the mixture was partiotionated between EtOAc and a 1M aq. NaHCO3 sol. The organic layer was separated, dried over MgSO4 and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 1:1) provided 171 mg (0.38 mmol, 83%) 2-Ethylsulfanyl-6-[(4-fluoro-benzoyl)-methyl-amino]-N-[(3-fluorophenyl)-methyl]-4-methyl-pyridine-3-carboxylic acid amide (example 120). [M+H]+456.1
