Procedure
To a solution of 6-(4-trifluoromethyl-phenyl)-pyridine-3-carbaldehyde (2.1 g, 8.3 mmol) in THF (20 mL) is added EtMgBr (3.0 M in Et2O, 3.2 mL, 9.6 mmol) at 0˜5° C., stirred for 2 hrs, quenched by NH4Cl aq., extracted with ethyl acetate, dried and concentrated giving 1-[6-(4-trifluoromethyl-phenyl)-pyridin-3-yl]-propan-1-ol (1.8 g) and [6-(4-trifluoromethyl-phenyl)-pyridin-3-yl]-methanol (0.29 g).
