2-(4-Bromophenyl)imidazo[1,2-a]pyridine → 2-(4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)imidazo[1,2-a]pyridine

Participants

Reaction Steps

2-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]imidazo[1,2-a]pyridine was prepared from 2-(4-bromophenyl)imidazo[1,2-a]pyridine (0.273 g, 1.00 mmol) in a manner similar to that used for the preparation of N2-[2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1,3-benzoxazol-2-amine. The compound was formed as a white solid (0.250 g, 78%). RP-HPLC (25 to 100% CH3CN in 0.1 N aqueous ammonium acetate over 10 min at 1 mL/min using a Hypersil HS C18, 250×4.6 mm column) Rt=11.35 min, 87%; m/z 321 (MH+).
