Reaction Steps

In a 20 mL scintillation vial, 4-amino-5-cyano-6-ethoxy-pyridine-2-carboxylic acid (19 mg, 0.09 mmol) was dissolved in DMA (0.7 mL). Then TBTU (30 mg, 0.09 mmol) dissolved in DMA (0.7 mL) was added, followed by the addition of 2-methylbenzylamine (12 mg, 0.11 mmol, 1.2 eq.) in DMA (0.6 mL). Then TEA (9.37 mg, 0.09 mmol) dissolved in DMA (0.7 mL) was added. The reaction mixture was shaken at room temperature for 24 hours. The crude mixture was purified using reverse phase HPLC (TFA). 1H NMR (500 MHz, DMSO-D6/D2O) δ ppm 1.31 (t, 3H) 2.28-2.34 (m, 3H) 4.38-4.55 (m, 4H) 7.05-7.10 (m, 1H) 7.11-7.21 (m, 4H) 8.92-8.99 (m, 1H). MS (ESI) positive ion 311 (M+H)+; negative ion 309 (M−H)−.
