25% | With caesium carbonate; In N,N-dimethyl-formamide; at 65℃; for 18h; | EXAMPLE 42-(2-Chloro-4-iodorhohenylaminoV5.5-dimethyl-8-oxo-5,6J.8-tetrahvdro-4H-thienor2,3- clazepine-S-carboxylic acid ethyl ester; Caesium carbonate (2.77 g, 8.51 mmol) and 2-chloro-4-iodo-l-fluorobenzene (2.18 g, 8.51 mmol) were added to a solution of Intermediate 6 (2.0 g, 7.09 mmol) in DMF (20 mL) and heated at 650C for 18 h. Brine (100 mL) was added to the reaction and the mixture extracted with DCM (3 x 50 mL). The combined organic extracts were dried (MgSO4) and concentrated in vacuo. The residual DMF was azeotroped with heptane. The crude product was purified by chromatography (silica, 0-30% EtOAc in DCM) to give the title compound as a cream solid (916 mg, 25%). deltaeta (DMSO-d6) 10.60 (IH, s), 8.01 (IH, t, J 5.0 Hz), 7.95 (IH, d, J2.0 Hz), 7.78 (IH, dd, J 8.6, 2.0 Hz), 7.54 (IH, d, J 8.6 Hz), 4.32 (2H, q, J 7.1 Hz), 2.91 (2H, s), 2.85 (2H, d, J 5.2 Hz), 1.33 (3H, t, J 7.1 Hz), 0.99 (6H, s). LCMS (ES+) RT 3.81 minutes, 519 (M+H)+. |
