실험 절차
[2-(3-Trifluoromethyl-phenyl)-cyclopropyl]-methanol obtained in step 1 (0.250 g, 1.15 mmol) was taken in diethyl ether (4 ml) and cooled to 0° C. Tribromo phosphine (0.06 ml, 0.64 mmol) in diethyl ether (4 ml) was added slowly at 0° C. and stirred at 15-20° C. for 2 hrs. Reaction mixture was quenched with saturated NaHCO3 solution (20 ml) and extracted with diethyl ether. Organic layer was washed with saturated brine solution, dried over Na2SO4, and evaporated under vacuum to get 1-(2-bromomethyl-cyclopropyl)-3-trifluoromethyl-benzene (0.26 g, 80%) as a sticky mass.
