Reaction Conditions:
with water;sodium hydroxide at 100; for 2 h;Temperature;
Steps:
1.3; 21-28; 29; 30; 2.3; 3.3
General procedure: 3), the 2-methoxy-4-nitroacetanilide obtained in the step 2) is added to 200 g of water, and 48.0 g (1.2 mol) of sodium hydroxide is added.After heating to 100 ° C, the hydrolysis reaction was kept for 2 h.GC detection of 2-methoxy-4-nitroacetanilide has been completed,The reaction solution was cooled to 0 to 5 ° C and filtered.The obtained filter cake is washed (300 ml of deionized water),Drying (drying to constant weight at 80 ° C) gives the product 2-methoxy-4-nitroaniline 159.4g,The yield was 94.8%,
