Reaction Steps

To the solution of tert-butyl 4-(2-(methylsulfinyl)benzo[d]thiazol-6-yloxy)picolinate (500 mg, 1.25 mmol) in 10 ml of NMP was added (1R,2R)-cyclohexane-1,2-diamine (581 mg, 3.84 mmol) and DIPEA (0.995 ml, 5.76 mmol). The reaction solution was stirred at 100° C. for 3 days. The crude reaction solution was purified on prep HPLC and evaporated in vaccuo to give tert-butyl 4-(2-((1R,2R)-2-hydroxycyclohexylamino)benzo[d]thiazol-6-yloxy)picolinate (240 mg, 0.544 mmol) as white powder. ES/MS m/z 442.5 (MH+).
