실험 절차
Methyl 2-cyclohexene-1-carboxylate (4.0 g; 28.5 m. moles) was added to a solution of sodium (0.73 g; 31.7 m. moles) in methanol (20 ml) and the mixture was allowed to stand at room temperature for a period of 21/2 hours. The mixture was poured into dilute hydrochloric acid, extracted with ether (4×25 ml) and the combined extracts washed with dilute aqueous sodium carbonate and then water. The dried (MgSO4) extract was evaporated and the residue distilled to give methyl 1-cyclohexene-1-carboxylate (3.5 g; yield 87.5%), b.p. 84° C./15 mm.
