Procedure

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 NMP (1 ml) were added 229 μl (1.35 mmol) DIPEA and 39 μl (0.50 mmol) chloroacetone. The mixture was heated in the MW to 140° C. for 40 min and subsequently partiotionated between a 1M aq. NaOH sol and EtOAc. The organic layer was separated, washed with a 1M aq. NaOH sol, water and brine, dried over MgSO4 and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 13:7) provided 53 mg (0.14 mmol, 30%) 2-Ethylsulfanyl-N-[(3-fluorophenyl)-methyl]-4-methyl-6-[methyl-(2-oxo-propyl)-amino]-pyridine-3-carboxylic acid amide (example 253). [M+H]+ 390.2
