実験手順

A mixture of 0.17 g (0.285 mmol) [(3S,4R)-1-(5′-Acetyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carbonyl)-4-(4-fluoro-phenyl)-pyrrolidin-3-yl]-ethyl-carbamic acid 4-fluoro-phenyl ester (example 38) and 84.3 mg (0.295 mmol) 5,5-dibromobarbituric acid in 10 mL dioxane was heated to 85° C. for 40 h. At room temperature 0.216 g (2.95 mmol) diethylamine was added and heated to 45° C. for 2 h and evaporated. the residue was taken up in methanol and subjected to preparative HPLC on reversed phase eluting with a gradient formed from acetonitrile, water and NEt3. The product containing fractions were evaporated to yield 49 mg (26%) of the title compound as light brown solid. MS m/e: 648.3 [M+H]+.
