実験手順

A mixture of 40.1 parts of 2,5-dihydroxyphenyl benzyl ketone, 42.7 parts of isodecylbromide, 48.5 parts of potassium carbonate and 400 parts of dry acetone was stirred under reflux for 120 hours. On cooling to 20° C the inorganic salts were filtered off and the acetone filtrates evaporated to give a brown oil. This residue was dissolved in 200 parts of petroleum ether, filtered to remove insoluble matter, and then washed with 4 × 50 parts of N sodium hydroxide solution and finally with water. The petrol solution was dried and evaporated to yield 42.4 parts of 2-hydroxy-5-isodecyloxyphenyl benzyl ketone as a brown oil.
