Reaction Conditions

Reaction Steps

To a solution of ethyl 3,3-bis(4-fluorophenyl)propanoate, prepared in the previous step, in THF (75 mL) at −78° C. was added LAH (1 M in PhMe, 35 mL, 35.0 mmol). The reaction mixture was warmed to 0° C. over 15 min, quenched with 6 mL of water, 12 mL of 2.5 M NaOH, followed by 18 mL of water. The mixture was stirred at room temperature for 30 min. The solids were removed by filtration and the solution was concentrated to provide 3,3-bis(4-fluorophenyl)propan-1-ol which was used in the next step without further purification.
