反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: The title compound was prepared using analogous conditions to those described in Example 1 utilizing 5-(2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)pyrazin-2-amine and 1-(2-bromophenyl)-N-methylmethanesulfonamide. MS (ESI): mass calcd. for C18H17FN4O2S, 372.11; m/z found, 373.1 [M+H]+. 1H NMR (400 MHz, CD3OD) δ 8.34 (s, 1H), 8.25 (s, 1H), 7.99 (m, 1H), 7.68-7.60 (m, 1H), 7.50-7.40 (m, 2H), 7.39-7.31 (m, 3H), 4.36 (s, 2H), 2.49 (s, 3H).

実験手順: To a solution of (2-bromophenyl)methanesulfonyl chloride (2 g, 7 mmol) in THF (15 mL) was added CH3NH2/H2O (25%, 2 g, 20 mmol) at 0° Celsius. The resulting mixture was warmed up to rt, stirred for 16 hours, concentrated to dryness and purified by HPLC to give the title compound (0.8 g, 41%). MS (ESI): mass calcd. for C8H8BrO2S, 262.96; m/z found, 264.0 [M+H]+; 1H NMR (300 MHz, CDCl3) δ 7.65-7.54 (m, 2H), 7.35 (m, 1H), 7.22 (dd, J=7.6, 1.7, 1H), 4.53 (s, 2H), 4.10 (s, 1H), 2.72 (s, 3H). concentrated to dryness purified by HPLC
