반응 단계

(1R,28)-1-(1-(4-chlorophenyl)-1H-indazol-5-yloxy)-1-(3-methoxyphenyl)propan-2-amine (126a) (256 mg, 0.63 mmol) dissolved in NMP (3.5 mL) was added to a solution of 2,2-difluoropropanoic acid (111 mg, 1.00 mmol), HATU (382 mg, 1.00 mmol) and DIPEA (0.438 mL, 2.51 mmol) in NMP (1.5 mL). The reaction mixture was stirred at r.t. for 2 h. Additional 2,2-difluoropropanoic acid (80 mg, 0.73 mmol), HATU (278 mg, 0.73 mmol) and DIPEA (0.25 mL, 1.4 mmol) in NMP (1.5 mL) was added. The reaction mixture was stirrred at r.t. for another h. Water (50 mL) was added, the mixture was extracted with EtOAc (2×50 mL), the organic phase was washed with 10% NaHSO4 (aq), brine, dried over MgSO4, filtered and evaporated to give a crude product that was purified by HPLC. The fractions containing the product was combined and freeze dried. Yield 197 mg (62%).
