実験手順

2-Amino-N-[1-benzyl-5-(4-fluoro-phenyl)-1H-[1,2,4]triazol-3-yl]-2-methyl-propionamide (137 mg, 0.388 mmol), HATU (295 mg, 0.776 mmol), and picolinic acid (72 mg, 0.582 mmol) were stirred in DCM (6 mL). TEA (108 uL, 0.776 mmol) was added to the reaction mixture and it was stirred for 1 day. It was diluted with EtOAc (65 mL) and extracted with water (15 mL), followed by saturated NaHCO3 (15 mL). The organic layer was dried with a brine wash (10 mL) followed by Na2SO4. The solvents were removed in vacuo and the residue was purified by reverse phase HPLC (C18, 45-100% MeOH/H2O+5 mM NH4OH) followed by silica gel chromatography (0-30% ACN/DCM) to afford the title compound as a white solid: 1H NMR (400 MHz, DICHLOROMETHANE-d2) δ ppm 1.73 (s, 6H) 5.35 (s, 2H) 7.07-7.22 (m, 4H) 7.26-7.39 (m, 3H) 7.49 (ddd, J=7.61, 4.77, 1.14 Hz, 1H) 7.52-7.61 (m, 2H) 7.90 (td, J=7.74, 1.71 Hz, 1H) 8.19 (dt, J=7.77, 1.04 Hz, 1H) 8.47 (br. s., 1H) 8.58 (ddd, J=4.77, 1.61, 0.95 Hz, 1H) 9.45 (br. s., 1H); Rt (method A)=1.22 min, (M+H)+ 459.0.
