Procedure

2-(4-Methoxy-3,5-dinitro-phenyl)-2-methyl-propan-1-ol was dissolved in 5 mL of CH2Cl2. Acetic anhydride was added followed by DMAP. The mixture was stirred overnight, then diluted in 15 mL of CH2Cl2 and washed with 1 M NaSO4, saturated NaHCO3, and brine. The CH2Cl2 solution was then dried with Na2SO4, filtered, and concentrated to provide acetic acid 2-(4-methoxy-3,5-dinitro-phenyl)-2-methyl-propyl ester (628 mg) as a brown oil.
