Procedure

A mixture of 20.0 g. of methyl angelate, 22.65 g. of 3-methyl-3-butenyl alcohol, 100 ml. of toluene and 0.8 g. of dioctyltin laurate was reacted under the same conditions as in Example 6. The reaction mixture was subjected to single distillation to obtain 39.5 g. of a distillate boiling at 104° C. (32 mmHg).
