実験手順

6-(4-Bromo-2-methyl-phenylamino)-7-fluoro-3-(4-oxo-butyl)-3H benzoimidazole-5-carboxylic acid cyclopropylmethoxy-amide 11n (15 mg, 0.030 mmol) is dissolved in MeCN (500 μL) and methylpiperazine (10 μl, 0.089 mmol) is added followed by AcOH (5 μL, 0.089 mmol). After 5 minutes, tetramethylammonium triacetoxyborohydride (12 mg, 0.045 mmol) is added. After 5 minutes, the reaction mixture is diluted with ethyl acetate and washed with NaHCO3 and brine. The organic layer is dried (Na2SO4) and concentrated under reduced pressure to give 12 mg (69%) of pure desired product as a white solid. MS APCI (−) m/z 587, 585 (M−1 Br pattern) detected; 1H NMR (400 MHz, CDCl3) δ 7.99 (s, 1H), 7.98 (s, 1H), 7.30 (d, 1H), 7.08 (dd, 1H), 6.30 (d, 1H), 6.1 (broad singlet, 1H), 4.26 (t, 2H), 3.64 (d, 2H), 3.37 (s, 1H), 2.45 (broad, 8H), 2.41 (s, 3H), 2.38 (t, 2H), 2.28 (s, 3H), 1.95 (quin, 2H), 1.55 (quin, 2H), 0.98 (m, 1H), 0.50 (qt, 2H), 0.22 (qt, 2H).
