Procedure

The reaction of Example 1 was repeated except for using 45 g (0.5 mol) of dimethyl carbonate as a quaternizing agent in place of methyl 2-hydroxyisobutyrate. The reaction pressure was increased as the reaction proceeded and reached 3.5 MPa after 5 h as a result of the generation of carbon dioxide gas and methanol due to the decomposition of dimethyl carbonate.
