Reaction Conditions

Reaction Steps

To a solution of 80% acetic acid (104 mL AcOH/26 mL water) was added 32 (4.01 g, 6.48 mmol). The reaction mixture was heated at 90° C. overnight, cooled to r.t., to form a precipitate which was collected by filtration to afford intermediate 33 (2.4 g, 66% yield) as a beige solid. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 12.51 (s, 1H), 11.86 (s, 1H), 10.14 (s, 1H), 9.14 (s, 1H), 8.66 (d, J=5.6 Hz, 1H) 8.59 (s, 1H), 8.54 (d, J=8.0 Hz, 1H), 8.40 (d, J=8.4 Hz, 1H), 8.07 (d, J=12.8 Hz, 1H), 7.58 (s, 2H), 7.38 (t, J=7.2 Hz, 2H), 7.19 (t, J=8.6 Hz. 2H), 6.83 (d, J=5.6 Hz, 1H), 3.84 (s, 2H). MS (m/z): 560.9 (M+H).
