Reaction Steps

A solution of 254 mg (0.75 mmol) 6-chloro-2-ethylsulfanyl-N-[(4-fluorophenyl)-methyl]-4-methyl-pyridine-3-carboxylic acid amide (synthesized according to the methods described in sections a) and b) of example 2), 196 μl (2.25 mmol) morpholine and 392 μl (2.25 mmol) DIPEA in MeCN (2 ml) was heated in the microwave at 180° C. for 4 h. Subsequently the RM was diluted with water and EtOAc and the layers were separated. The organic layer was washed with water and brine, dried over MgSO4 and concentrated in vacuo. Crystallisation (hexane/EtOAc 1:1) of the residue yielded 154 mg (0.40 mmol, 53%) 2-ethylsulfanyl-N-[(4-fluorophenyl)-methyl]-4-methyl-6-morpholin-4-yl-pyridine-3-carboxylic acid amide (example 4). [M+H]+ 390.2.
