Procedure
To a suspension of 6-((5-bromo-1H-benzo[d]imidazol-1-yl)methyl)-2-(methylsulfinyl)benzo[d]thiazole (655 mg, 1.6 mmol) and (1R,2R)-2-aminocyclohexanol (558 mg, 4.8 mmol) in anhydrous DMA (3.0 mL) was added DIEA (842 μL, 4.8 mmol). The mixture was heated in a sealed tube at 110° C. for 18 h. The mixture was cooled to rt and added dropwise to a stirred solution of water causing a precipitate to form. After stirring for 10 min, the solid was collected by filtration to afford (1R,2R)-2-((6-((5-bromo-1H-benzo[d]imidazol-1-yl)methyl)benzo[d]thiazol-2-yl)amino)cyclohexanol (837 mg) as a tan solid. The material was used in the next step without further purification. 1H NMR (300 MHz, DMSO-d6) δ 8.46 (s, 1H), 7.97 (d, J=7.5 Hz, 1H), 7.85 (d, J=1.7 Hz, 1H), 7.65 (s, 1H), 7.54 (d, J=8.5 Hz, 1H), 7.26-7.39 (m, 2H), 7.19 (m, 1H), 5.47 (s, 2H), 4.74 (d, J=5.1 Hz, 1H), 3.51 (m, 1H), 3.32 (m, 1H), 2.01 (m, 1H), 1.87 (m, 1H), 1.55-1.67 (m, 2H), 1.13-1.32 (m, 4H); LCMS (ESI) m/z 457, 459 (M+H)+.
