실험 절차

This compound was prepared according to general method 2 with (step I) 2-(3-fluorophenyl)acetic acid (1.03 g; 7.57 mmol) and oxalyl chloride (0.704 mL; 8.33 mmol) in dichloromethane (5 mL) and a few drops of DMF and (step II) ethyl 2-amino-2-(hydroxyimino)acetate (1.0 g; 7.57 mmol) and N,N diisopropylethylamine (2.11 mL; 12.11 mmol) in dichloromethane (10 mL) and (step III) pyridine (18 mL). The crude material was purified by flash chromatography on silica (eluent 20 to 100% ethyl acetate in heptane) to yield 0.555 g (30%) of the title compound as a white solid.
