| production method | is obtained by reacting o-toluidine with ethyl acetoacetate. O-toluidine can also react with diketene: Add 400NL distilled water to a four-necked round-bottomed flask, start stirring, cool 10-15 ℃, add 32.1g of o-toluidine and 26.5g of diketene Dropwise at the same time with a 50ml burette evenly according to a certain flow ratio (the product precipitates out 10min after dropping), add it at 1.5H, and stir at 10-15 ℃ for 1H, it is obtained by Suction filtration and suction drying. The yield was 90.5%-90.9%, and the reaction was carried out under the conditions in the above test method using O-methoxyaniline instead of o-toluidine to give a white fine-grained product in a yield of 92%-94.2%. Industrial production of 1000kg product consumption: o-toluidine 620kg, acetoacetate 760kg. |
