Reaction Steps

A stirred mixture of 6-((5-methyl-1H-benzo[d]imidazol-1-yl)methyl)-2-(methylsulfinyl)benzo[d]thiazole (0.26 g, 0.76 mmol) from the previous step, (1R,2R)-2-aminocyclohexanol (0.26 g, 2.2 mmol), DIEA (0.98 g, 7.6 mmol) and NMP (2 mL) was heated at 130° C. for 12 h. The reaction mixture was cooled to rt, diluted with EtOAc (30 mL), and washed with water (10 mL×2). The organic layer was dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was purified by silica gel flash chromatography eluting with 3% MeOH in DCM to afford (1R,2R)-2-((6-((5-methyl-1H-benzo[d]imidazol-1-yl)methyl)benzo[d]thiazol-2-yl)amino)cyclohexanol (79 mg, 89%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 8.30 (s, 1H), 7.91 (d, J=7.5 Hz, 1H), 7.61 (d, J=2.0 Hz, 1H), 7.39-7.42 (m, 2H), 7.28 (d, J=8.1 Hz, 1H), 7.16 (dd, J=8.4, 1.8 Hz, 1H), 7.02 (d, J=7.2 Hz, 1H), 5.42 (s, 2H), 4.69 (d, J=5.1 Hz, 1H), 3.39 (m, 1H), 3.33 (m, 1H), 2.38 (s, 3H), 2.03 (m, 1H), 1.86 (m, 1H), 1.59-1.63 (m, 2H), 1.21-1.23 (m, 4H); LCMS (ESI) m/z 393 (M+H)+.
