Versuchsvorschrift

5-Methoxy indanone was treated with aqueous formaldehyde in the presence of iron pentacarbonyl and KOH in ethanol according to G. Cainelli et. al., Tetrahedron Letters 27, 2491 (1973). After chromatography (hexane:ethylacetate=7:3) over SiO2, a 44% yield of white crystals was obtained (m.p. 73-76° C.).
