実験手順

In a high pressure reactor a solution of N-(2-fluoro-4-(trifluoromethoxy)benzyl)-5-((1-methyl-1H-pyrazol-3-yl)methoxy)-2-nitroaniline (80.0 g, 0.18 mol), 5% Pt/C (50% H2O, Johnson Matthey B102022-5) (7.1 g, 0.91 mmol) and ethyl acetate (800 mL) was filled twice with N2 (60 psi) then twice with H2 (60 psi). The flask was then filled with H2 (60 psi) and let stir at RT 15 h. The reaction mixture was filtered (zapcap brand filter), the solid was rinsed with EtOAc (2×200 mL). The filtrate was concentrated to dryness to afford the title compound as a brown oil (74.5 g, 99.5%). This material was used without further purification. MS (ESI): mass calcd. for C19H18F4N4O2, 410.1; m/z found, 411.1 [M+H]+. 1H NMR (600 MHz, CDCl3) δ 7.42-7.35 (m, 1H), 7.33-7.29 (d, J=2.2, 1H), 7.01-6.94 (d, J=9.2, 1H), 6.71-6.66 (d, J=8.3, 1H), 6.37-6.31 (dd, J=8.3, 2.7, 1H), 6.31-6.26 (m, 1H), 4.98-4.94 (s, 1H), 4.41-4.33 (s, 1H), 3.93-3.85 (s, 2H), 3.35-2.72 (s, 1H).
