1-Hydroxybenzotriazole → 8-Hydroxy-N-methyl-N-(4-(2-phenylpropan-2-yl)benzyl)quinoline-2-carboxamide

Participants

Reaction Steps

TEA (42 mg, 0.42 mmol), EDC.HCl (80 mg, 0.42 mmol), HOBt (57 mg, 0.418 mmol) and N-methyl-1-(4-(2-phenylpropan-2-yl)phenyl)methanamine (50 mg, 0.21 mmol) of Preparation 1 were sequentially added to a suspension of 8-hydroxyquinoline-7-carboxylic acid (48 mg, 0.25 mmol) in DCM (2.5 mL). The resulting reaction mixture was stirred at RT overnight. The mixture was quenched with H2O and then extracted three times with DCM. The separated organics were dried over Na2SO4, filtered and concentrated under reduced pressure. The residue was purified by flash chromatography (silica gel, DCM:MeOH 95:5) affording the title compound (39 mg, 0.1 mmol) as a grey solid. LC-MS m/z (ESI+): 411.2 (MH+), Rt=2.42 min (Method A).
