実験手順
4-Amino-5-chloro-2-fluorobenzoic acid tert-butyl ester (Intermediate 177; 3.0 g, 12.21 mmol) was dissolved in DCM (75 mL) and trifluoroacetic acid (25 mL) added. The mixture was stirred for 1 hour at room temperature and then concentrated to yield the title compound as a pale yellow solid (2.45 g, 100%).
