실험 절차

To a solution of 4-(2-(5-((tert-butoxycarbonyl(methyl)amino)methyl)pyridin-2-ylamino)thiazol-5-ylthio)-3-fluoropicolinic acid (120 mg, 0.244 mmol) and 1-amino-2-phenylpentan-2-ol (1.3 eq, 0.317 mmol, 57 mg) in NMP (4 mL) was added HOBT (1.3 eq, 0.317 mmol, 43 mg), EDAC (2 eq, 0.488 mmol, 94 mg) and diisopropylethylamine (5 eq, 1.22 mmol, 157 mg, 213 uL). The reaction was stirred at 23° C. overnight. The product was precipitated by addition of water to the reaction mixture. The solid was isolated by filtration to give the crude title material (97 mg, 61%) as a solid which was used as such in the next reaction. 1H NMR (400 MHz, DMSO-d6) δ ppm: 0.76 (3H, t, J=7.33 Hz), 0.90 (1H, m), 1.18-1.32 (1H, m), 1.41 (9H, s), 1.65-1.84 (2H, m), 2.75 (3H, s), 3.62 (2H, d, J=5.81 Hz), 4.32 (2H, s) 7.04 (1H, t, J=5.18 Hz), 7.11 (1H, d, J=8.59 Hz), 7.20 (1H, t, J=7.33 Hz), 7.31 (2H, t, J=7.71 Hz), 7.44 (2H, d, J=7.33 Hz), 7.66 (1H, s), 7.82 (1H, s), 8.13-8.32 (3H, m), 11.93 (1H, s). LC/MS (M+H)+: 653. Ret. time: 2.257 (Condition A).
