Water → 4-[1-Hydroxycyclohept-1-yl-1-(imidazolyl)methyl]benzonitrile

Participants

Reaction Steps

10 g of 4-[1-(imidazolyl)methyl]benzonitrile is dissolved in 270 ml of tetrahydrofuran and combined at -50° with 40 ml of 1.5-molar solution of lithium diisopropylamide in tetrahydrofuran, stirred for 0.5 hour at -60° combined with 6 5 g of cycloheptanone, stirred further for 1 hour, and heated to 25°. Then water is added, the mixture is diluted with ethyl acetate, washed neutral with water, dried over sodium sulfate, and concentrated to dryness under vacuum, thus producing 16 g of crude 4-[1-hydroxycyclohept-1-yl-1-(imidazolyl)methyl]benzonitrile.
