Isopropyl iodide → 3-(Benzyloxy)-5-bromo-1-(propan-2-yl)pyridin-2(1H)-one

Participants

Reaction Steps

3-(Benzyloxy)-5-bromopyridin-2(1H)-one (200 mg, 0.714 mmol), Cs2CO3 (302 mg, 0.928 mmol), and 2-iodopropane (0.086 mL, 0.857 mmol) were combined in DMF (3 mL) at RT. After stirring overnight the mixture was concentrated. The residue was taken up in CH2Cl2, filtered through a pad of Celite®, and concentrated. Flash column (Biotage-SNAP-10 g, 0-30% EtOAc/hexanes) gave the title compound as a clear oil (58 mg, 25%) which solidified under vacuum. 1H NMR (400 MHz, CDCl3): δ 7.46-7.29 (m, 5 H); 7.05 (d, J=2.4 Hz, 1 H); 6.66 (d, J=2.4 Hz, 1 H); 5.34-5.25 (m, 1 H); 5.09 (s, 2 H); 1.35 (d, J=6.8 Hz, 6 H). LC/MS (M+H)+ 322/324.
