Versuchsvorschrift
A solution of 3.1 g. spiro(cyclohexane-1,2'-indan)-4-one oxime [12] (prepared in Example 24B) and 6 ml. of acetic anhydride in 25 ml. of pyridine is allowed to stand at room temperature for about 6 hours. The reaction mixture is then poured into ice: water and the solid collected on a filter. The solid is recrystallized from Skellysolve B to give 2.94 g. (88% yield) of spiro(cyclohexane-1,2'-indan)-4-one, oxime acetate [13] having a melting point of 91° to 94° C.
