Reaction Steps
To mixture of enantiomer 2 of 4-{1-ethyl-1-[4-(2-hydroxy-3,3-dimethyl-butoxy)-3-methyl-phenyl]-propyl}-2-methyl-benzoic acid (0.70 g, 1.70 mmol) and DMF (5 mL) is added hydroxylamine hydrochloride (0.18 g, 1.87 mmol), EDCI (0.33 g, 1.87 mmol), HOBt (0.23 g, 1.87 mmol), and NEt3 (0.95 mL, 6.79 mmol). The mixture is stirred at ambient temperature overnight, diluted with EtOAc (40 mL), washed with 1M HCl (40 mL), water (40 mL), brine (40 mL), dried over MgSO4, filtered and concentrated to furnish the title compound (0.76 g, 2.19 mmol, 81%).
