Reaction Steps

A mixture of 61 g. (0.29 m.) of 4-methoxy-3-nitrophenyl acetate (part B) and 34.68 g. (0.87 g. (0.87 m.) of NaOH in 500 ml. of H2O was stirred and heated on a steam bath for 2 hours. The reaction solution was acidified with 87 ml. of conc. HCl, keeping the temperature below 20°C. The acid solution was extracted three times using a total of 1500 ml. of benzene. The combined benzene extracts were dried over anhydrous MgSO4, filtered and concentrated in vacuo to give 33 g. m.p. 78°-80°.
