Reaction Steps

A suspension of 5-bromo-1-(2-(7-methoxyquinolin-4-yloxy)propyl)pyridin-2(1H)-one (20 mg, 51 μmol), thiophen-2-ylboronic acid (13 mg, 103 μmol), 1,1′-bis(diphenylphosphino)ferrocene-palladium dichloride (2 mg, 3 μmol), and Na2CO3 (77 μl, 154 μmol) in DME (0.5 mL) was heated to 80° C. for 2 h. The mixture was purified on RP-HPLC and the product was netralized with CH2Cl2/NaOH (1 M). The product was lyophilized from 1:1 acetonitrile/water (1 mL) to give a white fluffy powder. MS (ESI pos. ion) m/z (MH+): 393.
