Procedure
To a cold (−78° C.) solution of the 2-{[3,5-dimethyl-7-(1H-pyrazol-1-ylmethyl)tricyclo[3.3.1.13,7]dec-1-yl]oxy}ethanol (3.69 g) in tetrahydrofuran (50 mL) was added n-butyllithium (20 mL, 2.5 M in hexane) under nitrogen. The mixture was stirred at −78° C. for 1.5 hours. Iodomethane (10 mL) was added by syringe, and the mixture was stirred for an additional 3 hours. The reaction mixture was then quenched by the addition of aqueous ammonium chloride solution and extracted with ethyl acetate. The combined organic layers were washed with water and brine, dried with sodium sulfate, filtered and concentrated. The residue was purified by normal phase chromatography to give the title compound.
