Procedure
6.2 A suspension of 108 mg (0.253 mmol) of 1-[3-(2,5-dichlorophenyl)-4,5-dihydropyrazol-1-yl]-2-[3-(5-hydroxypyrimidin-2-yl)phenyl]ethanone, 100 mg (0.38 mmol) of triphenylphosphine and 64.4 μl of 2-morpholinoethanol in 0.5 ml of THF is cooled in an ice bath, and 74 μl (0.38 mmol) of diisopropyl azodicarboxylate are slowly added dropwise. The reaction mixture is stirred at room temperature for 16 hours. The mixture is evaporated and the residue is chromatographed on a silica-gel column with dichloromethane/methanol as eluent: 1-[3-(2,5-dichlorophenyl)-4,5-dihydropyrazol-1-yl]-2-{3-[5-(2-morpholin-4-ylethoxy)pyrimidin-2-yl]phenyl}-ethanone (“A8”) as colourless crystals; ESI 540;
