Versuchsvorschrift

A solution of 254 mg (0.75 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), 322 mg (2.25 mmol) N-methyl-1-(tetrahydro-2H-pyran-2-yl)methanamine and 392 μl (2.25 mmol) DIPEA in MeCN (2 ml) was heated in the microwave at 150° C. for 4.5 h. Subsequently the RM was diluted with a 2M aq. NaOH sol and EtOAc and the layers were separated. The organic layer was washed with water and brine, dried over MgSO4 and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 1:1) provided 122 mg (0.28 mmol, 38%) 2-ethylsulfanyl-N-[(3-fluorophenyl)-methyl]-4-methyl-6-[methyl-(tetrahydro-pyran-2-yl-methyl)-amino]-pyridine-3-carboxylic acid amide (example 5). [M+H]+ 432.2.
