반응 단계
A solution of 47.5 parts of (-)-ethyl 1-(1-phenylethyl)-1H-imidazole-5-carboxylate sulfate in 500 parts of water is alkalized with 14 parts of sodium hydroxide solution 50%. The product is extracted twice with 325 parts of dichloromethane. The combined extracts are dried, filtered and evaporated in vacuo. The residue is crystallized from 2,2'-oxybispropane, yielding (-)-ethyl 1-(1-phenylethyl)-1H-imidazole- 5-carboxylate.
