実験手順
To the solution of [4-(4-Chloro-phenyl)-thiazol-2-yl]-methanol (0.80 g, 3.55 mmol) in 10 ml of toluene was added PBr3 (0.51 ml, 5.33 mmol) and the reaction mixture was heated at 120° C. for 20 min under nitrogen atmosphere. After the completion of the reaction mixture (TLC monitoring), water (25 mL) was added and extracted with ethyl acetate (3×50 mL). The combined organics was washed with water, brine, dried (Na2SO4), filtered and concentrated to get the desired product (0.17 g, 17%). The corresponding cyano derivative was also prepared by the same general method.
