Versuchsvorschrift
A mixture of 1.4 g of 2-tetralone, 1.5 mL of methyl orthoformate, and a few crystals of para-toluenesulfonic acid monohydrate in 75 mL of benzene was stirred for 22 hours and then evaporated in vacuo. The residue was chromatographed on Florisil® eluting with hexane/ethyl ether to provide 1.15 g (75%) of the desired title intermediate. NMR.
