概要
- 論文の詳細を見る
The nitrosation of 1-(2-chloroehtyl)-and 1-cyclohexyl-3-(3-pyridyl) methylureas with sodium nitrite and hydrochloric acid, gave a mixture consisting of the corresponding 1-and 3-nitroso derivatives. These isomers were successfully separated by fractional crystallization using diethyl ether. Their structures were confirmed by means of nuclear magnetic resonance spectroscopy and chemical reaction.
