Reaktionsschritte

A solution of Compound 1086 (90 mg, 0.2438 mmol), triphenylphosphine (76.74 mg, 0.2926 mmol), diisoproplylazodicarboxylate (59.17 mg, 56.68 μL, 0.2926 mmol), and (S)-tetrahydrofuran-3-ol (25.78 mg, 0.2926 mmol) in THF (90 μL) was heated at 70° C. for 10 minutes under microwave irradiation. The reaction was quenched with ammonium chloride (satd') and extracted with EtOAc. The organics were washed with 1 M NaOH (2×), brine, dried over sodium sulfate, and concentrated under vacuum. The residue was chromatographed over silica gel (0-50% EtOAc/hexanes gradient) to give 3-(1-(4-((R)-tetrahydrofuran-3-yloxy)-2,3-difluorophenyl)-1H-tetrazol-5-yl)-5-bromopyridin-2-amine (Compound 1090, 99 mg).
