反応手順
N2-[2-Fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]-5,7-dimethyl-1,3-benzoxazol-2-amine was prepared from N2-(4-bromo-2-fluorophenyl)-5,7-dimethyl-1,3-benzoxazol-2-amine (6.500 g, 19.39 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 pink solid (3.549 g, 48%). 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=15.50 min, 78%; m/z 383 (MH+).
