实验步骤: 1-[3-(Dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (1.71 g), 1-hydoxybenzo-triazole hydrate (1.24 g), and 2-(benzo[1,3]dioxol-5-yloxy)-nicotinic acid were combined and suspended in anhydrous dichloromethane (40 mL). N,N-diisopropylethylamine (5.93 mL) was added to the suspension, which was stirred for 0.5 h. The suspension was added to (4-aminomethyl-phenyl)-acetic acid methyl ester (1.22 g) and the reaction mixture stirred at ambient temperature overnight. Water (approx. 15 mL) was then added to the reaction mixture, and it was extracted with dichloromethane (7×30 mL). The combined organics were dried over magnesium sulfate, filtered, and concentrated in vacuo. The crude product was purified by silica gel chromatography (ethyl acetate:hexanes=3:2) to yield the title compound (1.41 g). the reaction mixture stirred at ambient temperature overnight was extracted with dichloromethane (7×30 mL) The combined organics were dried over magnesium sulfate filtered concentrated in vacuo The crude product was purified by silica gel chromatography (ethyl acetate:hexanes=3:2)

实验步骤: Palladium hydroxide (Pearlman's catalyst, 1.04 g) was added to a solution of conc. aq. ammonium hydroxide:methanol (1:4) (50 mL) in a Parr flask. (4-Cyano-phenyl)-acetic acid methyl ester (1.00 g) was added to the solution. The Parr flask was then shaken for 20 min under hydrogen (50 psi). The reaction mixture was filtered (nylon 66) and the filtrate concentrated in vacuo to yield crude title compound (1.22 g). The reaction mixture was filtered (nylon 66) the filtrate concentrated in vacuo
