実験手順
A solution of 5.4 g of sodium methylate in 64 g of methanol was added to a mixture of 192 g of methyl cis trans-3-pentenoate, 4 g of methyl 2-cis-pentenoate and 28 g of methyl 2-trans-pentenoate, and the mixture was heated to 65° C. and stirred for four hours at this temperature. After the working up procedure described in Example 1, 153.6 g (53% of theory) of methyl 3-methoxyvalerate were obtained.
