Reaction Steps

To a suspension of (2-bromobenzo[d]thiazol-6-yl)methanol (400 mg, 1.6 mmol) from Step 2 of Example 2 in DMA (6 mL) were added DIEA (258 mg, 2.0 mmol) and (1R,2R)-2-aminocyclohexanol (226 mg, 2.0 mmol) at rt. The reaction mixture was stirred in a sealed tube at 120° C. overnight. After cooling to rt, the mixture was concentrated under reduced pressure to give crude (1R,2R)-2-((6-(hydroxymethyl)benzo[d]thiazol-2-yl)amino)cyclohexanol as a brown oil (445 mg, 100%), which was used for the next step without any further purification. LCMS (ESI) m/z 279 (M+H)+.
