実験手順
Prepared from ethyl 2-(3-fluoro-4-(thieno[3,2-b]pyridin-7-yloxy)phenylamino)-2-oxoacetate (Example 2; 36 mg, 0.10 mmol) and pyrrolidine (36 mg, 0.50 mmol) according to the procedure for Example 3. The product was purified on a pre-packed Isoelute silica gel column (10 g silica), eluting with a gradient of 20% EtOAc/hexanes, 1:1 EtOAc/hexanes, 2:1 EtOAc/hexanes, and then neat EtOAc. The product was obtained as a white powder (33 mg, 86%). 1H NMR (400 MHz, CDCl3) δ 9.74 (s, 1H), 8.52 (d, J=5 Hz, 1H), 7.87 (m, 1H), 7.75 (d, J=6 Hz, 1H), 7.58 (d, J=6 Hz, 1H), 7.37 (m, 1H), 7.26 (m, 1H), 6.52 (d, J=5 Hz, 1H), 4.09 (t, J=7 Hz, 2H), 3.63 (t, J=7 Hz, 2H), 2.02 (m, 2H), 1.91 (m, 2H). LRMS (ESI pos) m/e 386 (M+1). HPLC: 100% purity (220 nm).
