Reaction Steps

A mixture of 0.015 g (0.038 mmol) of [3′-(3-chloro-benzoylamino)-5′-cyano-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl]-acetic acid, 0.019 g (0.19 mmol) of 4-hydroxypiperdine, 0.016 g (0.049 mmol) of 0-(benzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium tetrafluoroborate, and 0.016 mL (0.11 mmol) of triethylamine in N,N-dimethylformamide (2 mL) is allowed to stir at room temperature overnight. The mixture is concentrated under reduced pressure and the residue is diluted with water which results in a solid precipitating. The light red solid is collected by filtration and washed with water. The collected material is purified using preparative reverse phase HPLC to give 0.011 g (61%) of the title compound (145) as a colorless solid. [M+H]+=482.2
