Reaction Steps

3,3-Dimethylcyclohexanone (5.60 mL) was added to sodium bis(trimethylsilyl)amide (45.3 mL, 1M in tetrahydrofuran), and the reaction was stirred for 1 hour. tert-Butyl 4-(bromomethyl)piperidine-1-carboxylate (11.1 g) in dimethylsulfoxide (30 mL) was added, and the reaction was stirred at 50° C. for 24 hours. The reaction was cooled, poured into water (300 mL), extracted three times with ether, and the combined extracts were washed three times with water, and brine, dried over Na2SO4, filtered, and concentrated. The crude product was chromatographed on silica gel using 5-20% ethyl acetate in hexanes to provide the title compound.
