実験手順
A solution of 5-amino-2-fluorobenzoic acid (300 mg, 1.9 mmol), diisopropylethylamine (1 ml, 5.8 mmol), and isopropylamine (0.3 ml, 3.9 mmol) in acetonitrile was heated to 110° C. in microwave for 45 min. This reaction was repeated 5 times and the crude products combined then concentrated in vacuo. The residue was purified by flash chromatography (SiO2) eluting with ethyl acetate/dichloromethane (0% to 10% v/v) to afford the title compound as a yellow solid (2.31 g). HPLC retention time 3.93 min. Mass spectrum ES+) m/z 197 (M+H).
