| NIST chemical information | information provided by: webbook.nist.gov (external link) |
| Use | an intermediate of amobarbital. |
| production method | bromination of isoamyl alcohol with hydrogen bromide-sulfuric acid to produce 1-bromo-3-methylbutane, it is then condensed with diethyl malonate in the presence of sodium ethoxide to give diethyl α-isoamyl malonate. The latter is made by condensation (ethylation) with bromoethane in the presence of sodium ethoxide. |
