Reaction Steps

A mixture of Example 360 (100 mg, 0.18 mmol), 3-(tert-butoxycarbonylamino)-pyrrolidine (66 mg, 0.35 mmol), potassium tert-butoxide (28 mg, 0.25 mmol) and acetato(2′-di-tert-butylphosphino-1,1′-biphenyl-2-yl)palladium(II) (20 mg, 0.043 mmol) in 1,4-dioxane (2.0 mL) was heated in a sealed tube at 100° C., under microwave irradiation, for 2 h. The solvent was removed in vacuo and the residue was purified by column chromatography (SiO2, 0-100% EtOAc/heptane). The obtained solid was taken up in DCM (10 mL), treated with a solution of HCl in Et2O (2M, 1.0 mL, 2.0 mmol) and stirred at room temperature for 18 h. The solvent was removed in vacuo and the residue was purified by column chromatography (0-20% MeOH/DCM) to give the title compound (36 mg, 38%) as an orange solid. δH (CD3OD) 8.89-8.77 (1H, m), 8.57-8.44 (1H, m), 8.22-8.09 (1H, m), 7.62-7.51 (1H, m), 7.38-7.20 (2H, m), 7.02 (1H, d, J 7.7 Hz), 4.22-4.08 (1H, m), 3.93-3.48 (8H, m), 3.27-3.05 (4H, m), 2.81 (2H, s), 2.68-2.45 (3H, m), 2.38-2.21 (1H, m), 1.08 (6H, s). LCMS (ES+) 503.4 (M+H)+.
