Reaction Steps

To a solution of 3-amino-phenol (60 g, 6.55 mol) in 2 N NaOH (1 l), cooled to 10° C., pivaloyl chloride (68 ml, 0.55 mol) in toluene (200 ml) is added within 1 h. After stirring for 15 h at 25° C., the mixture is cooled to 0° C. and acidified to pH 1 with conc. HCl. Extraction with EtOAc washing with water, 10% NaHCO3, water, and brine, followed by drying (Na2SO4), evaporation of volatiles, and crystallization (EtOAc/hexanes) gives N-(3-hydroxy-phenyl)-2,2-dimethyl-propionamide.
