Procedure

The reaction was carried out similarly as described in the preparation of compound 148, using compound 452 (0.13 mmol) and 3,4-dichloro-phenylamine (0.13 mmol). The crude product was purified by continuous gradient flash chromatography using MeOH/DCM/petroleum ether (40-60) 0:50:50, 0:100:0 and 5:95:0 as the eluent to afford the title compound as yellow solid. 13C NMR (DMSO-d6) δ 196.4, 146.4, 145.6, 142.0, 141.9, 141.6, 135.3, 134.9, 134.3, 132.1, 131.5, 131.0, 127.6, 122.5, 120.6, 120.5, 119.7, 118.6, 118.4, 112.2, 60.1, 29.1, 21.8, 18.8
