Reaction Conditions:

with water;chloroacetic acid ethyl ester in ethyl acetate for 0.416667 h;Microwave irradiation;

Steps:

3 Example 3: Preparation of 4-methyl-2-(1H)-quinolinone
In a 50mL pressure-resistant reaction tube, 4-3.4% quinoline was added in sequence, Ethyl chloroacetate 1.23g, Distilled water 0.54g, 20 ml of ethyl acetate, The resulting mixture was subjected to microwave irradiation for 25 minutes in a 300 W microwave stirring reaction apparatus. Washing the reaction solution with hot water, Liquid separation, Collect organic phase, Ethyl acetate and ethyl chloroacetate were removed under reduced pressure. Recrystallization to give the corresponding 4-methyl-2-(1H)-quinolinone 1.50g, The yield was 94%.
