Use | pharmaceutical intermediates. |
production method | 1, 3-bromochloropropane and diethyl malonate are used to form cyclobutyl -1 under the action of sodium ethoxide, the Diethyl ester of 1-dicarboxylic acid is then hydrolyzed and decarboxylated to give cyclobutyl carboxylic acid, which is hydrogenated to give cyclobutyl methanol and then brominated to give the product. |
