Versuchsvorschrift
To a suspension of 4-chloro-5-(4-chlorophenyl)isoxazole-3-carboxylic acid (0.66 g, 2.58 mmol) and oxalyl chloride (0.9 mL, 10.32 mmol) in dichloromethane (30 mL) was added 2 drops of N,N-dimethylformamide. After the mixture was stirred 16 hours at room temperature, the volatiles were removed in vacuo to obtain 4-chloro-5-(4-chlorophenyl)isoxazole-3-carbonyl chloride (0.71 g, 2.53 mmol).
