実験手順

To a solution of 4-chloro-3-fluorobenzaldehyde (1 eq) in THF (0.3 M) at −78° C. was added 3M/Et2O MeMgBr (1.5 eq). The reaction mixture was stirred at −50° C. for 3 hrs, quenched with aqueous saturated NH4Cl and extracted with EtOAc. The combined organic layers were dried over Na2SO4 and concentrated to give 1-(4-chloro-3-fluorophenyl)ethanol, which was used as such for the next step.
