Reaction Steps

2-((3-benzyl-5-phenylpyrazin-2-yl)amino)butanoic acid was dissolved in DCM (10 mL). Pyridine (0.5 mL) was added followed by N,N′-Dicyclohexylcarbodiimide (137 mg, 0.67 mmol). The reaction mixture was slowly stirred at room temperature for 1 hr. The solvent was evaporated, and the residue purified by flash chromatography (eluting solvent: EtOAc to DCM to 10% methanol in DCM) to give the product as a yellow powder (110 mg, 89%). 1H NMR (300 MHz, CD3OD, δ): 7.26 (m, 3H), 6.84-7:07 (m, 8H), 4.03 (s, 2H), 2.47 (q, J=9.0 Hz, 2H), 0.96 (t, J=9.0 Hz, 3H); MS (ESI): m/z 330.2 (M+1).
