Procedure

To a solution of tert-butyl 4-(7-(2-fluoro-4-nitrophenoxy)thieno[3,2-b]pyridin-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate 267 (1 g, 2.13 mmol) in DCM (4.3 mL) TFA (4.3 mL) was added and the reaction mixture was stirred for 2 h at room temperature. The solvent was removed under reduced pressure, the residue was suspended in aqueous sodium bicarbonate, the mixture extracted with DCM, EtOAc and DCM; the combined organic phases were filtered and the recovered solids dried. The organic phase was dried over anhydrous Na2SO4, concentrated under reduced pressure and the residue was combined with the solid material obtained earlier to provide 268 (806 mg, 2.12 mmol, 100% yield) as a yellow solid. MS (m/z): (M+1) 372.1 (100%).
