Ammonia → Cyclohexanecarboxamide, 2-(hydroxymethyl)-, (1S,2R)-(9CI)

Participants

Reaction Steps

(1R,6S)-(+)-8-oxabicylo[4.3.0]nonan-7-one (1 gram) was dissolved in 5 ml of absolute ethanol, followed by the addition of 0.5 gram of gaseous ammonia. The solution was kept in a stoppered flask, and the progress of the reaction was followed by thin layer chromatography (eluent dichloromethane/methanol 20:1). After the reaction was judged complete, the ethanol was evaporated and the resulting residue redissolved in ethyl acetate. Ammonia was removed by extraction with 1% HCl, and the ethyl acetate solution was dried over MgSO4, filtered, and rotary evaporated to leave 0.7 grams of (1S,2R)-2-hydroxymethyl-1-cyclohexanecarboxamide.
