実験手順
In a pressure-resistant sealed vessel, were dissolved 1.14 g of o-chlorobenzoic acid (7.3 mM) and 0.18 g of cuprous chloride (1.8 mM) in 5 g of an isobutyl alcohol solution containing 20% dimethylamine (about 6.0 ml) prior to addition of isobutyl alcohol to a total volume of 50 ml, followed by heating to 100° C. as in Example 4. The reaction mixture solution was analyzed periodically over time by GC-MSE1 in the same manner as in Example 4, in order to follow the progress of the reaction. As a result, 20 hours later, the completion of the reaction was confirmed. Effecting the subsequent process in the same manner as in Example 4, 1.0 g of 2-isobutoxybenzoic acid was obtained (yield of 70.6%). The ester of the above product (3%) and benzoic acid (5%) were also obtained as the byproducts, which were confirmed by 1H-NMR and GC-MSE1.
