실험 절차
To a suspension of (E)-3-[4-({4-[3-(trifluoromethyl)phenyl]-1-piperazinyl}sulfonyl)phenyl]-2-propenoic acid (9a) (0.30 g, 0.69 mmol) in dichloromethane (7 mL) oxalyl chloride (0.2 mL, 2.4 mmol) and a drop of dimethylformamide were added. The reaction mixture was stirred at ambient temperature for 0.5 hours and at 42° C. for 1 hour. The reaction mixture was evaporated and the residue was dried in vacuum to give (E)-3-[4-({4-[3-(trifluoromethyl)phenyl]-1-piperazinyl}sulfonyl)phenyl]-2-propenoyl chloride (10a) (0.31 g) in a form of a crude product.
