Potassium Hydroxide → 1-(3-Bromophenyl)cyclohexanecarboxamide

Participants

Reaction Steps

With overhead stirrer, a mixture of crude product from step 1, above, (380 g, 1207 mmol), powdered KOH (720 g) and t-BuOH (2.5 L) was heated at reflux overnight. See Hall, J. H.; Gisler, M. A simple method for converting nitriles to amides. Hydrolysis with potassium hydroxide in tert-butyl alcohol. J. Org. Chem. 1976, 41, 3769-3770. If deemed complete by GC analysis, it was cooled with ice-water (cool slowly to avoid shock to the glass), quenched with ice-water (1500 mL). The quenched mixture was then extracted with MTBE (3.5 L+1.5 L). MTBE layers were concentrated to a yellow solid, 390 g.
