Vorschrift

2-Benzylidene-1-indanone [3.3 g (0.015 mole), prepared as described in U.S. Pat. No. 3,926,988] is dissolved in 160 ml of MeOH and converted to the epoxide using 3.5 g (0.031 mole) of 30% H2O2 and 3.5 ml (0.014 mole) of 16% NaOH as described in Example 1 to give 3.2 g (90%) of colorless solid; m.p. 115°-117°. A sample crystallized from i-PrOH melts at 118°-120°. Lit m.p. 121°-122° [JACS, 80, 900 (1958)].
