実験手順
2.5 mL of Diisopropylazodicarboxylate in 1.5 mL of THF was added dropwise to a solution of 250 mg of (6-methylpyridin-2-yl)methanol, 2.8 g of Triphenylphosphine and 1.6 g of isoindoline-1,3-dione in anhydrous THF at room temperature. The reaction was stirred for 2 hours and monitored by TLC. Upon complection, the solvent was concentrated, the crude material was extracted in water and Chloroform 3 times and dried over Magnesium Sulfate. The crude was purified via ISCO Combi-Flash to yield 2-((6-methylpyridin-2-yl)methyl)isoindoline-1,3-dione. 350 mg of 2-((6-methylpyridin-2-yl)methyl)isoindoline-1,3-dione was treated with 440 μL of Hydrazine Monohydrate in EtOH and refluxed for several hours to yield (6-methylpyridin-2-yl)methanamine. The crude (6-methylpyridin-2-yl)methanamine was evaporated and directly coupled to 50 mg of 3-chloro-4-(4-chloro-3-(pyridin-2-yl)phenylcarbamoyl)benzoic acid via Procedure G. The crude product was purified on reverse phase HPLC to yield 2-chloro-N1-(4-chloro-3-(pyridin-2-yl)phenyl)-N4-((6-methylpyridin-2-yl)methyl)terephthalamide. MS (Q1) 491.1 (M)+.
