Benzoyl chloride → HCID 46186187, compound

Participants

Reaction Steps

To a cooled mixture (0° C.) of 16 (65 mg, 0.17 mmol) in CH2Cl2 (3 mL) were added Et3N (100 μL, 4.2 equiv.) and benzoyl chloride (30 μL, 1.5 equiv.). The mixture was stirred for 12 h at room temperature. The resulting mixture was then quenched at 0° C. with NaHCO3. It was extracted with the mixture of EtOAc. The resulting organic layer was washed with saturated aqueous NaHCO3 solution and brine, dried over MgSO4, filtered and solvents were removed under reduced pressure. The crude product was purified by flash chromatography (EtOAc/PE 1:1) to afford 17 in 48% yield as a white solid, 1H NMR (300 MHz, CDCl3): δ 8.48 (d, 1H, J=2.3 Hz), 8.41 (d, 1H, J=8.5 Hz), 8.13-8.11 (m, 3H), 7.77 (bs, 1H), 7.70 (d, 1H, J=7.5 Hz), 7.57-7.41 (m, 7H), 6.19 (bs, 1H), 3.05 (q, 2H, J=6.9 Hz), 3.09 (t, 2H, J=6.9 Hz); MS (ESI) m/z 490 [M+H+]
