実験手順
Oxalyl chloride (60 mL, 686 mmol) and dimethylformamide (DMF) (8 drops, cat.) were added to a stirred suspension of 2-(4-fluorophenoxy)ethanoic acid (97.3 g, 572 mmol) in dichloromethane (500 mL). After 22 hours, the mixture was concentrated under vacuum to obtain 108 g of 2-(4-fluorophenoxy)ethanoic acid chloride, a compound of formula (Y), as a yellow oil in quantitative yield; 1H NMR (CDCl3) δ 4.90 (s, 2H), 6.84 (m, 2H), 6.99 (m, 2H) ppm.
