N2-(4-bromo-2-fluorophenyl)-1,3-benzothiazol-2-amine → N2-[2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1,3-benzothiazol-2-amine

Reaction Steps

N2-[2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1,3-benzothiazol-2-amine was prepared from N2-(4-bromo-2-fluorophenyl)-1,3-benzothiazol-2-amine (1.699 g, 5.258 mmol) in a manner similar to that used for 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 an off-white powder (0.825 g, 42%). 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) tr=14.48 min, 90%; m/z 371 (MH+).
