Participants

Reaction Steps

The reaction was carried out similarly as described in the preparation of compound 148, using compound 452 (0.13 mmol) and 3,4-difluoro-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, 149.6 (dd), 147.5, 145.7, 144.7 (dd), 142.3, 142.2, 138.4 (dd), 135.3, 135.2, 134.4, 132.1, 127.0, 120.7, 120.5, 118.4, 117.9 (d), 117.7, 116.0 (dd), 111.4, 108.5 (d), 60.2, 29.2, 22.0, 18.9
