Participants

Reaction Steps

To a solution of (1S)-2-[bis(phenylmethyl)amino]-1-[3-({3-[(phenylmethyl)oxy]propyl}oxy)phenyl]ethanol (240 mg, 0.50 mmol) in 5 mL of toluene at −20° C. was added 1.75 mmol of nBuLi in hexane (2.59 M, 0.67 mL) over about 5 minutes. The mixture was then stirred for 2 h and then quenched with freshly distilled trimethylborate (0.28 mL, 259 mg, 2.5 mmol). The cold bath was removed and the mixture warmed to room temperature. The reaction was then diluted with 10 mL of TBME, then 5 mL of saturated NaHCO3 solution was added. After vigorously stirring for about 30 min, the organic layer was washed with 5 mL of 0.1 M NaH2PO4, then 5 mL of saturated NaHCO3. The organic layer was then dried over Na2SO4 and concentrated.
