Dimethylformamide (5 mL) was added to a solution of 3-[3-(trifluoromethyl)phenyl]prop-2-en-1-ol (50 g) in dichloromethane (500 mL) at 0 to 5° C. Thionyl chloride (44.2 g) was slowly added to the above mixture maintaining the temperature at about 0 to 5° C. The reaction mixture was stirred at 0 to 5° C. for 1-2 hours. After completion of the reaction, the mixture was quenched with ice-chilled de-ionized water (250 mL) at 0-10° C. and stirred for 30 minutes. Organic layer was separated, washed twice with a solution of sodium chloride (10%; 250 mL) and concentrated under vacuum to give 1-[3-chloroprop-1-en-1-yl]-3-(trifluoromethyl)benzene.
