実験手順
To a solution of 3-methoxy-4-[2-(1-pyrrolidinyl)ethoxy]aniline (43 mmol, 10.0 g) in DCM was added triethylamine (52 mmol, 5.2 g) and 4-chloro-2-nitrobenzoyl chloride (9.5 g, 43 mmol). The solution was stirred overnight. The reaction mixture was extracted with 2N HCl. The resulting acidic aqueous solution was made basic by adding 2N NaOH. The combined basic aqueous solution was extracted with DCM. The organic phase was washed with brine, dried and concentrated giving the title compound (11.5 g, 69%). 1H NMR (DMSO-D6): δ 1.66 (4H, m), 2.49 (4H, m), 2.75 (2H, t, J=6.0 Hz), 3.72 (3H, s), 4.00 (2H, t, J=6.0 Hz), 6.94 (1H, d, J=8.6 Hz), 7.14 (1H, d, J=8.6 Hz), 7.79 (1H, d, J=8.1 Hz), 7.94 (1H, d, J=8.1 Hz), 8.23 (1H, s), 10.55 (1H, s). LCMS m/z=420 (m+H+).
