Versuchsvorschrift

To a solution of N-{1-[4-(3-methoxypropoxy)-1-benzofuran-6-yl]ethyl}-cyclopropanamine (200 mg) and (2R)-4-(tert-butoxycarbonyl)morpholine-2-carboxylic acid (240 mg) in N,N-dimethylformamide (7 mL) were added 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (212 mg) and 1-hydroxybenzotriazole (140 mg) under ice-cooling, and then stirred at room temperature for 18 hours. To the reaction mixture was added aqueous saturated sodium hydrogen carbonate solution, and the mixture was extracted with ethyl acetate. The organic layer was sequentially washed with water, 10% aqueous citric acid solution and saturated saline, and then concentrated under reduced pressure to give tert-butyl (2R)-2-[(cyclopropyl{1-[4-(3-methoxypropoxy)-1-benzofuran-6-yl]ethyl}amino)carbonyl]morpholine-4-carboxylate [Ex(161-1)] (306 mg) as a yellow oil.
