Procedure

To a 0° C. mixture of 9.66 g (59.6 mmol) of 6-methoxy-l-indanone and 6.32 g (59.6 mmol) of benzaldehyde in 10 ml ethanol was added 9.66 ml of a 4% KOH in ethanol solution. The reaction was stirred 1 hour and then added to 300 ml water and the pH of the quench adjusted to 2 with 1N hydrochloric acid. The resultant mixture was extracted with 3×300 ml ether, and the extracts combined, dried over MgSO4, evaporated and the residue triturated with ether to yield 10.8 g (72%) of present title compound as a solid.
