Reaction Steps

A stirred mixture of 6-((5-fluoro-1H-benzo[d]imidazol-1-yl)methyl)-2-(methylsulfinyl)benzo[d]thiazole (0.20 g, 0.57 mmol) from the previous step, (1R,2R)-2-aminocyclohexanol (0.20 g, 1.7 mmol), DIEA (0.73 g, 5.7 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 separated, 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-fluoro-1H-benzo[d]imidazol-1-yl)methyl)benzo[d]thiazol-2-yl)amino)cyclohexanol (75 mg, 33%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 8.45 (s, 1H), 7.93 (d, J=7.2 Hz, 1H), 7.65 (d, J=1.5 Hz, 1H), 7.56 (m, 1H), 7.43 (dd, J=9.6, 2.4 Hz, 1H), 7.28 (m, 1H), 7.19 (dd, J=8.4, 1.8 Hz, 1H), 7.08 (dt, J=9.6, 3.0 Hz, 1H), 5.46 (s, 2H), 4.69 (d, J=5.4 Hz, 1H), 3.51 (m, 1H), 3.37 (m, 1H), 2.01 (m, 1H), 1.87 (m, 1H), 1.59-1.63 (m, 2H), 1.15-1.23 (m, 4H); LCMS (ESI) m/z 397 (M+H)+.
