Reaction Steps

A mixture of 2-(methylsulfinyl)-6-((6-(trifluoromethyl)-3H-imidazo[4,5-b]pyridin-3-yl)methyl)benzo[d]thiazole (180 mg, 0.45 mmol), (1R,2R)-2-aminocyclohexanol (112 mg, 0.97 mmol) and DIEA (261 mg, 2 mmol) in DMA (2 mL) was stirred at 130° C. overnight. The reaction mixture was diluted with EtOAc and washed with brine. The organic layer was dried over NaSO4, filtered and concentrated under reduced pressure. The residue was purified by preparative HPLC to afford (1R,2R)-2-((6-((6-(trifluoromethyl)-3H-imidazo[4,5-b]pyridin-3-yl)methyl)benzo[d]thiazol-2-yl)amino)cyclohexanol as a yellow solid (64 mg, 31.8%). 1H NMR (300 MHz, DMSO-d6) δ 8.84 (s, 1H), 8.78 (d, J=1.2 Hz, 1H), 8.55 (d, J=1.5 Hz, 1H), 7.95 (d, J=7.8 Hz, 1H), 7.68 (d, J=1.5 Hz, 1H), 7.29 (d, J=7.8 Hz, 1H), 7.25-7.22 (m, 1H), 5.55 (s, 2H), 4.71 (d, J=5.1 Hz, 1H), 3.52-3.50 (m, 1H), 3.37-3.33 (m, 1H), 2.08-2.01 (m, 1H), 1.87-1.85 (m, 1H), 1.64-1.60 (m, 2H), 1.29-1.19 (m, 4H). LCMS (ESI) m/z 448 (M+H)+.
