Procedure:
Methanesulfonyl chloride (229 g) was added dropwise to a solution (800 ml) of t-butylamine (420 g) in chloroform under cooling in an ice bath for 90 minutes. After stirring for 3 hours at room temperature, the solution was refluxed under heating for 1 hour. The resulting reaction mixture was cooled with ice, made acidic by adding dilute hydrochloric acid, and extracted with chloroform. The organic layer was washed with water and dried over sodium sulfate. The resulting solution was distilled under reduced pressure to obtain N-t-butylmethanesulfonamide (244 g) as white solid. This product was immediately subjected to the next step.

Procedure:
Next, 0.03 g of Pd(OAc)2 and 3.5 g of 1-(5-bromo-2-methoxyphenyl) adamantane were added to the mixture, followed by 25 mL of tetrahydrofuran in order to improve agitation, and the mixture was heated at reflux for approximately 24 hours. The resulting mixture was then evaporated to dryness and poured into 103 mL of 0.015 N HCl. Next, 150 mL of dichloromethane and 100 mL of water were added to yield a mixture consisting of a solid, an aqueous layer and an organic layer. The mixture was then filtered to separate the solid, the aqueous layer was discarded, and the organic layer was washed with 200 mL of water and decanted again. This process was repeated twice on the filtered solid. The three collected organic layers were evaporated to dryness, washed in methanol, and dried to yield 2.1 g of 3,3′-diadamantyl-4,4′-dimethoxybiphenyl (yield: 39.9%).

Procedure:
Sodium hydride (60%; 349 mg; 8.7 mmol) was suspended in DMF (3 mL) and cooled to 0° C. under inert atmosphere. Cyclopentylmethanol (0.79 mL; 7.3 mmol) was added dropwise to the sodium hydride mixture. The solution was allowed to warm to room temperature and stirred for 20 minutes. The solution was then added dropwise to a solution of 2,6-difluorobenzonitrile (1.03 g; 7.4 mmol) in DMF (3 mL) cooled to 0° C. The mixture was allowed to warm to room temperature and stirred for 4 hours. The solution was poured over 50 mL of cooled water and extracted with ethyl acetate and solvent removed. Purification by column chromatography (5% ethyl acetate/hexane) yielded 1.66 grams of 2-fluoro-6-(cyclopentylmethoxy)benzonitrile.
