Cyclohexyl methyl ketone → HCID 54220593, compound

Participants

Reaction Steps

A sodium ethoxide solution (21% by weight in ethanol, 6.805 gm, 21 mmol) was added to a mixture of 1-cyclohexyl-1-ethanone (18.749 g, 140 mmol, from Aldrich) and 4-fluorobenzaldehyde (17.37 g, 140 mmol, from Aldrich) in ethanol (100 ml), stirring under argon. The solution was allowed to stir 1.5 hours. The reaction mixture was then concentrated to afford an orange oil. The oil was dissolved in ether, washed with saturated NH4Cl and brine, then dried over Na2SO4, filtered and concentrated to an orange oil. The oil was purified by distillation (bp=143° C. at 1.3 mm Hg). The resultant yellowish oil slowly solidified to afford the title compound as hard yellow crystals (22.640 gm, 65%).
