Participants

Reaction Steps

131 mg (0.5 mmol) triphenylphosphane are added to a solution of 100 mg (0.41 mmol) 3-[5-(4-chloro-phenyl)-pyridin-2-yl]-prop-2-yn-1-ol and 88 mg (0.5 mmol) 4-pyrrolidin-1-ylmethyl-phenol in 4 mL THF. Then 0.1 mL (0.5 mmol) diisopropyl azo-dicarboxylate is slowly added dropwise and the reaction mixture is stirred for 3 h at RT. The mixture is evaporated down i. vac., the residue is taken up in 1 mL DMF and purified by HPLC. The product obtained, which still contains triphenylphosphane oxide, is again purified by chromatography (silica gel, EtOAc after EtOAc/MeOH/NH3 9:1:0.1).
