실험 절차

A solution of 700 mg (2.24 mmol) 2,6-dichloro-N-(3-fluorobenzyl)-4-methyl-pyridine-3-carboxylic acid amide (synthesis is described in section a) of example 2), 280 μl (2.9 mmol) thiomorpholine and 3.95 g (12.1 mmol) Cs2CO3 in dioxane (60 ml) was degassed for 30 min followed by the addition of 285 mg (0.25 mmol) Pd(PPh3)4. Subsequently the reaction solution was heated to 120° C. for 16 h. Then the mixture was filtered through celite and concentrated in vacuo. Purification of the residue by CC (hexane/EtOAc 19:1) provided 420 mg (1.1 mmol, 49%) 2-chloro-N-(3-fluorobenzyl)-4-methyl-6-thiomorpholino-pyridine-3-carboxylic acid amide.
