Reaction Steps
A solution of pyrazine-2-carboxylic acid (127 mg, 1.02 mmol) and DCC (211 mg, 1.02 mmol) in acetonitrile (5 mL) was added to a stirring solution of C-[1-(3-fluoro-4-thiomorpholin-4-yl-phenyl)-1H-[1,2,3]triazol-4-yl]-methylamine (200 mg, 0.68 mmol), obtained in Example 19, in dry acetonitrile (10 mL) and allowed to stir at room temperature for 6 h. The reaction mixture was then poured into ice-cooled water and extracted with ethyl acetate (20 mL×2). The organic portion was washed with water followed by brine and dried over sodium sulfate. Upon concentration and purification by silica gel column chromatography (acetone/chloroform, 15:85) the title compound was obtained (245 mg, 90%). Mp. 216-218° C.
