Yield: 96%
Reaction Conditions:
with toluene-4-sulfonic acid in water at 51 - 153; under 3750.38 Torr; for 6 h;Autoclave;Temperature;
Steps:
8 Example 8
In the autoclave was added 21 ° C hot water 2160g,Methyl anthranilate 217.6 g (1 mol, content 99.3%),P-Toluenesulfonic acid 22.0g (content of 98%), naphthyl oxyacetic acid methyl ester, catalyst and water mass ratio of 1: 0.1: 10.Heated up to 0.5MPa (about 153 ° C ),Adjust the vent to maintain the reaction pressure, venting methanol vapor through the condenser to condense methanol aqueous solution. Pressure-keeping reaction for 6 hours.After the reaction was completed, the mixture was slowly vented and cooled to 50 ° C with stirring.Filtered while hot, 100g70-80 hot water wash the filter cake 3 times, dried to give the product 197.1g, purity 98.5%, yield 96%.
