Reaction Steps
Sodium hydride (0.054 g, 1.3 mmol, 60% dispersion in mineral oil) was added to a mixture of trans-4-(benzo[d]thiazol-2-ylamino)cyclohexanol (0.17 g, 0.67 mmol) in NMP (1.5 mL) in a microwave tube. The tube was sealed and placed under an argon atmosphere. The mixture was stirred at RT for 45 min before 3-(3,6-dihydro-2H-pyran-4-yl)-2-fluoropyridine, as prepared in preparation 1a, step 1, (0.10 g, 0.56 mmol) was added via syringe. The reaction mixture was warmed to 120° C. and stirred for 1 h. Water was added, and the aqueous mixture was extracted with EtOAc (2×). The organic extracts were combined, washed with saturated sodium chloride, dried over magnesium sulfate, filtered, and concentrated. The resulting crude product was purified via silica gel chromatography to give both N-(trans-4-(3-(3,6-dihydro-2H-pyran-4-yl)pyridin-2-yloxy)cyclohexyl)benzo[c/]thiazol-2-amine and N-(trans-4-(3-(3,4-dihydro-2H-pyran-4-yl)pyridin-2-yloxy)cyclohexyl)benzo[d]thiazol-2-amine as white solids. [M+1] 408.1 each. IC50 (uM): 0.007281 (Example 3b) and 0.9154 (Example 3c).
