실험 절차

To a mixture of 3-hydroxy-4-fluorobenzoic acid (1.56 g, 10 mmol), cyclopropylamine (0.6 g, 10.5 mmol), triethylamine (1.02 g, 10 mmol) and HOBt (0.3 g, 2 mol) in DMF (10 mL) was added EDCI (2.0 g, 10.5 mmol) at RT. The mixture was stirred at RT overnight. The mixture was diluted with water and extracted with ethyl acetate (3×20 mL). The extract was washed with water and concentrated to afford 3-hydroxy-4-fluoro-N-cyclopropylbenzamide as a solid (1.2 g, 61.5%).
