Procedure
A solution of 410 mg (1.2 mmol) 6-chloro-2-ethylsulfanyl-N-[(3-fluorophenyl)-methyl]-4-methyl-pyridine-3-carboxylic acid amide (synthesis is described in section b) of example 2), 125 mg (1.0 mmol) 3-methoxy-azetidine and 824 mg (2.53 mmol) Cs2CO3 in 1,4-dioxane (7 ml) was heated at 110° C. for 24 h. Subsequently the RM was concentrated in vacuo. The residue obtained was partitioned between water and EtOAc. The organic layer was separated, dried over MgSO4 and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 3:1) provided 122 mg (0.31 mmol, 31%) 2-ethylsulfanyl-N-[(3-fluorophenyl)-methyl]-6-(3-methoxy-azetidin-1-yl)-4-methyl-pyridine-3-carboxylic acid amide (example 6). [M+H]+390.2.
