Reaction Steps
A mixture of 4-hydroxybenzoic acid (20.29 g, 147 mmol), N,O -dimethylhydroxylamine hydrochloride (21.49 g, 220 mmol), N-ethyl-N-isopropylpropan-2-amine (77 mL, 441 mmol), hobt (22.50 g, 147 mmol), and EDC (33.8 g, 176 mmol) in DMF (100 mL) was stirred at RT in 24 h. H2O was added, extracted with ether (3×), dried over MgSO4, concentrated, and purified by ISCO (40% EtOAc/Hexanes) to give the titled compound. MS [M+1]: 182.1.
