Procedure

In the same 100 ml autoclave as in Example 1, 1.5 g of tungstosilicic acid, 40 ml of mesitylene and 2.55 ml of γ-butyrolactone were charged and reacted at 180° C. for 6 hours, and then analysis was conducted. As a result, the conversion ratio of γ-butyrolactone was 85.1% and 2,4,6-trimethylphenylbutyric acid (yield based on γ-butyrolactone: 33.5%) was obtained.
