Versuchsvorschrift

To a solution of 6-[1-(tert-butoxycarbonyl)piperidin-4-yl]pyridine-2-carboxylic acid (247 mg) in dichloromethane (5 ml) are added, at room temperature, N-methyl-1,2,3,4-tetrahydronaphthalen-1-amine (130 mg), 4-dimethylaminopyridine (10 mg) and 1-ethyl-3-(3′-dimethylaminopropyl)carbodiimide (162 mg). The mixture is stirred at room temperature overnight, and then water is added. The aqueous phase is removed and extracted with ethyl acetate. The combined organic phases are dried over sodium sulphate and concentrated under reduced pressure. The residue is purified by chromatography. This gives tert-butyl 4-{6-[methyl(1,2,3,4-tetrahydronaphthalen-1-yl)carbamoyl]pyridin-2-yl}piperidine-1-carboxylate (219 mg).
