Procedure

N2-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-1,3-benzothiazol-2-amine was prepared from N2-(4-bromophenyl)-1,3-benzothiazol-2-amine (0.909 g, 2.98 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 (0.321 g, 31%). 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=13.82 min., 92%; m/z 351 (MH+).
