To a 250-mL flask under nitrogen is added 14.8 g (0.13 mol) of potassium tertiary butoxide followed by 74 mL of tetrahydrofuran. The solution is stirred for 10 minutes, suction filtered, and washed using 50 mL of tetrahydrofuran. The filtrates are combined and transferred into an additional funnel on a separate 250-mL flask containing 20 g (0.12 mol) of dried 1-cyanocyclohexaneacetic acid and 100 mL of tetrahydrofuran. The potassium tertiary butoxide solution is added dropwise over 5 minutes to the previous solution. The precipitate is cooled in an ice bath, suction filtered, and washed with 25 mL of cold tetrahydrofuran. The filter cake is dried in a vacuum oven at 50° C. for 16 hours to give 24.8 g of potassium 1-cyanocyclohexaneacetate as a white crystalline solid; mp 196°-199° C.
