Participants

Reaction Steps

To a solution of 0.13 g (0.19 mmol) 5′-{[2-(3,5-bis-trifluoromethyl-phenyl)-2-methyl-propionyl]-methyl-amino}-4′-(4-fluoro-2-methyl-phenyl)-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-sulfonic acid in 2 ml dichloromethane were added 0.33 ml (0.39 mmol) oxalyl chloride and one drop of DMF at 0° C. After 30 min the reaction mixture was allowed to warm to room temperature during 2 h. To the yellow reaction mixture were added 1.8 ml (20 mmol) of an aqueous solution of dimethylamine (60%). After 1 h the reaction mixture was diluted with water and extracted with three portions of dichloromethane. The combined organic extracts were dried over sodium sulphate and concentrated. Flash column chromatography gave 92 mg (69%) of the title compound as a white solid.
