Reaction Conditions

Reaction Steps

Add a solution of t-BuLi (20 mL, 26.0 mmol) via syringe to a solution of 3-bromo-phenol (2.06 g, 12 mmol) in THF (20 mL) at −78° C. under N2. After being stirred at −78° C. for 1 hour, add a solution of (1R,2R,4S,5S)-2,6,6-trimethyl-4-((methyl(phenethyl)amino)methyl)bicyclo[3.1.1]heptan-3-one (2.99 g, 10 mmol) in THF (2 mL) to the reaction mixture and stir the reaction mixture at −78° C. for additional 2 hours. Quench the reaction with saturated NH4Cl solution (30 mL). Extract the aqueous mixture with EtOAc (60 mL×3). The combined organic layers are washed with brine (30 mL), dried over Na2SO4, filtered, and concentrated under vacuum. Purify the residue by Preparative HPLC to give (1R,2R,3S,4S,5S)-3-(3-hydroxyphenyl)-2,6,6-trimethyl-4-((methyl(phenethyl)amino)methyl)bicyclo[3.1.1]heptan-3-ol as pale yellow oil (0.27 g, yield: 6.9%), MS (m/z): 394 (M+1).
