实验步骤: 1-Methyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzoimidazole-5-carboxylic acid (3-methylsulfanyl-propyl)-amide (69 mg) was prepared by following General Procedure F using 1-methyl-2-(6-trifluoromethoxy-benzothiazol-2-ylamino)-1H-benzimidazole-5-carboxylic acid (82 mg), 3-methylthio-propylamine (38 mg), HBTU (76 mg), and DIEA (0.2 ml). LC/MS: m/z 497.

实验步骤: 4-Chloro-6-(1H-indazol-4-yl)-1-methyl-1H-pyrazolo[3,4-b]pyridine 7 (100 mg) and 3-(methylthio)propylamine (3 equiv.) were heated in microwave at 170° C. for one hour following General Procedure B. Volatiles were removed in vacuo; the residue was purified by prep HPLC to give [6-(1H-indazol-4-yl)-1-methyl-1H-pyrazolo[3,4-b]pyridin-4-yl]-(3-methylsulfanyl-propyl)-amine (94 mg) as a white solid. 3-Chloroperoxybenzoic acid (MCPBA, 94 mg, 2.2 equiv.) in 2 ml dry DCM was added at 0° C. The reaction mixture was allowed slowly to warm up to room temperature over 3 hours and extracted with DCM, washed with saturated aqueous sodium hydrogen carbonate and purified by flash chromatography (methanol/DCM) to give 116 (27 mg) as a white solid. NMR (CDCl3): 2.39 (2H, m), 3.00 (3H, s), 3.25 (2H, t), 3.74 (2H, m), 4.20 (3H, s), 5.20 (1H, br t), 6.77 (1H, s), 7.50-7.54 (1H, m), 7.59 (1H, d), 7.70 (1H, d), 7.97 (1G=H, s), 8.82 (1H, s), 10.20 (1H, br). MS: MH+ 385.19 (100%) Volatiles were removed in vacuo the residue was purified by prep HPLC

实验步骤: Following a procedure analogous to the procedure described in Example 1 using N-{5-[5-(2-chloro-4-pyrimidinyl)-2-(1-methylethyl)-1,3-thiazol-4-yl]-2-fluorophenyl}-1-methyl-1H-imidazole-4-sulfonamide (75 mg, 0.152 mmol) and [3-(methylthio)propyl]amine (86 mg, 0.817 mmol) the title compound of Step B was obtained as a golden oil (76 mg, 89% yield). MS (ESI): 561.4 [M+H]+.
