3-溴-4-氧代哌啶-1-羧酸叔丁酯 - Reference Information
| Introduction | 3-bromo-4-oxopiperidine-1-carboxylic acid tert-butyl ester is an organic intermediate, which can be made of N-tert Butoxycarbonyl-4-piperidone is used as raw material and obtained after reacting with liquid bromine. |
| Uses | 3-bromo-4-oxopiperidin-1-carboxylic acid tert-butyl ester is an ester organic substance and can be used as an organic intermediate. |
| preparation | 19.9g (0.1 mol) N-tert-butoxycarbonyl -4-piperidone and 0.2 l chloroform were put into a 500 ml dry three-mouth bottle, and stirred under argon protection at 0 ℃ to obtain a light yellow clarified liquid. Slowly add 5.1 ml (0.1 mol) of bromine, the solution becomes brown liquid, and continue stirring for 2 hours to obtain light yellow clear liquid. After the reaction is complete, the vacuum concentrates the reaction solution to obtain a white powder. |
