Potassium Hydroxide → 5-bromo-1-(4-methoxybenzyl)-3-{1-[4-(morpholin-4-ylcarbonyl)phenyl]-1H-1,2,3-triazol-4-yl}-1H-indazole

Participants

Reaction Steps

4-methoxybenzylchloride (1.13 mL; 8.27 mmol; 1.5 eq.) was added dropwise to a solution of {4-[4-(5-Bromo-1H-indazol-3-yl)-[1,2,3]triazol-1-yl]-phenyl}-morpholin-4-yl-methanone (2.5 g; 5.5 mmol; 1.0 eq.) and KOH (0.34 g; 6.07 mmol; 1.1 eq.) in acetone (75 mL) and DMF (25 mL). The reaction mixture was stirred at RT O/N. It was then diluted with a 0.1N HCl solution and extracted three times with EtOAc. Combined organic phases were washed with brine, dried over magnesium sulfate, filtered and concentrated. The crude was purified by flash chromatography on silica (DCM:MeOH, gradient from 100:0 to 90:10) to give the title compound as an orange oil (4.1 g, 100%). UPLC/MS: (MS+) 573.0.
