Procedure

To a solution of [5-(4-fluoro-phenyl)-3-methyl-3H-[1,2,3]triazol-4-yl]-methanol (251 mg, 1.21 mmol) in THF (30 mL) was added 6-hydroxy-2-isopropyl-1H-pyrrolo[3,4-c]pyridin-3(2H)-one (232 mg, 1.21 mmol) and triphenylphosphine (413 mg, 1.58 mmol) at ambient temperature under an argon atmosphere. Then diethyl azodicarboxylate (624 μL, 1.58 mmol) was added and the reaction mixture was stirred for 72 h at room temperature. Concentration and purification by chromatography (silica, 20 to 50% ethyl acetate in heptane) afforded the title compound (87 mg, 19%) as a white solid. MS: m/e=382.2 [M+H]+.
