実験手順

A mixture of 19.6 g. of methyl angelate, 22.2 g. of 3-methyl-2-butenyl alcohol, 100 ml. of toluene and 1.6 g. of dioctyltin laurate was placed in a glass flask which was equipped with a Soxhlet extractor filled with molecular sieve 4A on the top and a reflux cooler. The mixture was heated under reflux while returning the refluxed liquid through the molecular sieve 4A to the flask. The mixture obtained from the heating for a total of 26 hours was subjected to single distillation to give 24.24 g. of a distillate boiling at 102°-105° C. (25 mmHg).
