反応手順
Pyridine-2-carboxylate (Aldrich; 0.35 g, 2.84 mmol), 4-aminobenzylamine (Aldrich; 0.51 g, 4.26 mmol) and HATU (1.65 g, 4.26 mmol) were dissolved in DMF (7.5 ml). N,N-Diisopropylethylamine (1.5 ml, 8.53 mmol) was added and the mixture stirred at room temperature for 2 h. The mixture was absorbed on to an SCX column, washed with methanol and eluted with ammonia in methanol. Product containing fractions were concentrated and the residue purified by normal phase chromatography (2% MeOH/DCM) to give a yellow solid (440 mg). which was suspended in DCM/Et2O and filtered to give the title compound as a pale yellow solid (235 mg, 36%).
