Reaction Conditions

Reaction Steps

DMF (0.3 mL) was added to a solution of 3-(4-trifluoromethyl-phenyl)-acrylic acid (I-29a: 4 g, 0.018 mol) in DCM (30 mL). The reaction mixture was stirred at 0° C. under nitrogen atmosphere. This was followed by the addition of SOCl2 (2.62 g, 0.022 mol) and the resulting mixture was refluxed at 75° C. for 3 hours. The reaction was monitored by TLC (30% ethylacetate in hexane). The reaction mixture was cooled to room temperature and concentrated to afford the crude product which was dissolved in 1,4-dioxane and used in the next step without further purification.
