Procedure

A solution of 6-(4-bromo-2-chloro-phenylamino)-3-(4-chloro-butyl)-7-fluoro-3H-benzoimidazole-5-carboxylic acid cyclopropylmethoxy-amide 18ee (10 mg, 0.018 mmol), sodium iodide (14 mg, 0.092 mmol), and 1-methyl-piperazine (10 μL, 0.092 mmol) are stirred at 85° C. for three hours. The reaction mixture is diluted with ethyl acetate and washed three times with water, washed twice with saturated aqueous potassium carbonate, dried (Na2SO4) and concentrated under reduced pressure to a yellow oil. Flash column chromatography (1:1 dichloromethane/methanol followed by methanol followed by 20:1 methanol/triethylamine) yields clean product (8 mg, 72%) as an off-white foam. MS ESI (+) m/z 607, 609 (M+, Br pattern) detected. 1H NMR (400 MHz, DMSO-d6) δ 8.37 (s, 1H), 7.71 (s, 1H), 7.49 (d, 1H), 7.18 (dd, 1H), 6.40 (dd, 1H), 4.38 (t, 2H), 3.62 (d, 2H), 2.45 (broad, 8H), 2.41 (t, 2H), 2.28 (s, 3H), 1.96 (m, 2H), 1.54 (m, 2H), 1.07 (m, 1H), 0.50 (d, 2H), 0.22 (d, 2H).
