反応手順
In a procedure substantially like that of Example 1, a mixture of 60 grams of phenol and 8 grams of 2-butanone was reacted in the presence of 1 ml. of mercaptoacetic acid (a catalyst used in place of the octanethiol of Example 1) and 40 ml. of concentrated hydrochloric acid. The Parr bomb and gaseous nitrogen were not used in this procedure. The reaction temperature was about 55° C. The crude reaction product was recrystallized from benzene to yield 5.2 grams of the title compound, which was dried overnight at about 95° C.
