실험 절차
Using a method similar to Preparation 14 using 2,4-Difluoro-N-(4-fluoro-3-nitrophenyl)benzamide (Preparation 13) (1.0 g, 3.38 mmol), SnCl2.2H2O (3.8 g, 16.9 mmol), ethanol (25 mL), and concentrated HCl (25 mL), gives the title intermediate (803 mg, 89% yield): mass spectrum (ion spray): m/z=267.0 (M+1).
