Reaction Conditions:
with potassium carbonate in water at 60 - 75; for 6 h;Reagent/catalyst;Temperature;
Steps:
1 Example 1: Preparation of 4-piperidone-1-acetic acid (III)
In a 500 ml four-necked flask equipped with a stirring, thermometer, reflux condenser, and constant pressure dropping funnel,Add 60 grams of water, 34.5 grams (0.25 moles) of potassium carbonate,21.8 g (0.23 mol) of chloroacetic acid,Heat, keep between 60-65 ,A solution of 27.1 g (0.2 mole) of piperidin-4-one hydrochloride and 60 g of water was added dropwise,The addition was completed in about 2 hours, and then the reaction was stirred at 70-75 ° C for 4 hours.Cool to 20-25 ° C, 30wt% hydrochloric acid acidification system pH 2.5-3.0, filter, dry,There was obtained 28.95 g of 4-piperidone-1-acetic acid as a white solid,The yield was 92.2%, and the purity of the liquid phase was 99.3%.
