PROCESS FOR THE PRODUCTION OF 2-(METHYLTHIO)-DISODIUM BARBITURATE |
| 摘要 |
A process is disclosed for the production of 2- (methylthio)-disodium barbiturate by reacting thiourea, malonic acid dimethyl ester and sodium methanolate to form disodium thiobarbiturate. The disodium thiobarbiturate is then reacted with methyl bromide, optionally in the presence of a base, to form the desired end product.
