Reaction Conditions:
with tris-(dibenzylideneacetone)dipalladium(0);caesium carbonate;4,5-bis(diphenylphosphino)-9,9-dimethylxanthene in 1,4-dioxane at 130; for 2.33333 h;Sealed tube;Inert atmosphere;
Steps:
52.2 Example
Step 2[00220j Intl3 (2.32 g, 6.16 mmol) and cyclopropanecarboxamide (1.048 g, 12.31 mmol) were dissolved in dioxane (62 mL) and Pd2(dba)3 (564 mg, 0.6 16 mmol), Xantphos (534 mg, 0.924 mmol) and cesium carbonate (4.01 g, 12.3 mmol) were added.The vessel was evacuated three times (backfilling with nitrogen) and then sealed and heated to 130 °C for 140 minutes. The reaction was filtered through CELITE (eluting with ethyl acetate) and concentrated (on smaller scale this material could then be purified using preparative HPLC). The crude product was adsorbed onto CELITE using dichloromethane, dried and purified using automated chromatography (100% EtOAc)provide example 52 (1.22 g, 46% yield). ‘H NMR (500MHz, chloroform-d) ö 10.99 (s,1H), 8.63 (s, 1H), 8.18 (s, 1H), 8.10 (d, J=0.5 Hz, 2H), 7.81 (dd, J7.9, 1.7 Hz, 1H), 7.51(dd, J7.9, 1.4 Hz, 1H), 7.33 - 7.20 (m, 7H), 4.01 (d, J0.3 Hz, 3H), 3.82 (s, 3H), 1.73 -1.60 (m, 1H), 1.16 - 1.06 (m, 2H), 0.97 - 0.84 (m, 2H).
