Reaction Steps

Lithium (3S,4R)-4-[(5-chloro-thiophene-2-carbonyl)-amino]-1-{[2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenylcarbamoyl]-methyl}-pyrrolidine-3-carboxylate (example 41; 0.09 g) is dissolved in THF/DMF (1:1; 3 ml) and CDI (0.083 g) is added. The mixture is stirred for 1 h at 25° C., after that 2-(methylamino)-ethanol (0.03 ml) is added. The reaction mixture is stirred for 18 h at 25° C. and evaporated to dryness followed by flash chromatography over silica gel using DCM/MeOH/NH3 as eluent to yield 0.033 g (33.4%) (3S,4R)-4-[(5-chloro-thiophene-2-carbonyl)-amino]-1-{[2-fluoro-4-(2-oxo-2H-pyridin-1-yl)-phenylcarbamoyl]-methyl}-pyrrolidine-3-carboxylic acid (2-hydroxy-ethyl)-methyl-amide. White solid. MS 576.5 [M+H+].
