To a stirred solution of (1R,2R)-2-((6-((6-vinyl-3H-imidazo[4,5-b]pyridin-3-yl)methyl)benzo[d]thiazol-2-yl)amino)cyclohexanol (20 mg, 0.049 mmol) from Example 98 in 1:1 MeOH/THF (2 mL) was added Raney Ni (10 mg). The resulting mixture was stirred under a H2 balloon at rt for 4 h. LCMS analysis showed that the reaction was complete. The reaction mixture was filtered through a Celite plug and the filtrate was purified with preparative TLC to give (1R,2R)-2-((6-((6-ethyl-3H-imidazo[4,5-b]pyridin-3-yl)methyl)benzo[d]thiazol-2-yl)amino)cyclohexanol (6 mg, 30%). 1H NMR (300 MHz, DMSO-d6) δ 8.53 (br s, 1H), 8.26 (br s, 1H), 7.95 (d, J=12.4 Hz, 2H), 7.66 (br s, 1H), 7.25-7.42 (m, 1H), 7.06-7.25 (m, 1H), 5.45 (br s, 2H), 4.74 (d, J=4.5 Hz, 1H), 3.51 (br s, 1H), 2.73 (d, J=7.2 Hz, 2H), 2.04 (br s, 1H), 1.86 (br s, 1H), 1.62 (br s, 2H), 1.23 (t, J=6.8 Hz, 7H). LCMS (ESI) m/z 408 (M+H)+.
