実験手順

Compound 37 (0.42 g, 1.15 mmol) and 4-(4-amino-phenyl)-piperazine-1-carboxylic acid tert-butyl ester (0.64 g, 2.30 mmol) were dissolved in dioxane (2 mL), and this mixture was heated at 100° C. for 24 hours. The reaction was cooled to room temperature and diluted with ethyl acetate. This mixture was washed with water and brine. The organic layer was dried with sodium sulfate and purified by flash chromatography (ethyl acetate/hexane) to give compound 38 as a yellow solid (0.23 g, 33%). 1H NMR (500 MHz, DMSO-d6) δ ppm 9.18 (1 H, s), 7.97 (1 H, s), 7.55 (2 H, d, J=10 Hz), 7.37 (2 H, m), 7.31 (1 H, m), 7.12 (2 H, m), 6.89 (2 H, d, J=10 Hz), 4.68 (1 H, m), 3.44 (4 H, m), 3.00 (4 H, m), 1.91 (2 H, d, J=10 Hz), 1.72 (2 H, d, J=10 Hz), 1.57 (1 H, d, J=10 Hz), 1.41 (9 H, s), 1.35 (2 H, m), 1.14 (2 H, m), 0.92 (1 H, m); LCMS-ESI (POS), M/Z, M+1: Found 609.2, Calculated 607.2/609.2.
