The title compound was prepared by procedure C using 7-chloro-2-(3,4,5-trimethoxyphenyl)furo[3,2-b]pyridine (45.00 mg; 0.14 mmol; 1.00 eq.) instead of 7-chloro-2-iodo-furo[3,2-b]pyridine, and 3-fluoro-4-[(2-hydroxyethyl)-carbamoyl]benzeneboronic acid (35.14 mg; 0.15 mmol; 1.10 eq.) instead of 4-fluorophenylboronic acid and was obtained as a pale yellow solid (32 mg, 48%). (HPLC (method F): 99%, RT: 3.09 min); 1H NMR (500 MHz, DMSO-d6) δ [ppm] 8.60 (dd, J=5.1, 1.8, 1H), 8.38 (s, 1H), 8.12-8.06 (m, 2H), 7.89 (t, J=7.9, 1H), 7.79 (d, J=1.8, 1H), 7.71 (dd, J=5.1, 1.8, 1H), 7.33 (d, J=1.7, 2H), 4.80-4.73 (m, 1H), 3.92 (d, J=1.7, 6H), 3.74 (d, J=1.8, 3H), 3.57-3.51 (m, 2H), 3.37 (dd, J=12.0, 6.1, 2H); MS (m/z) 467 [M+H]+, RT: 3.0 min.
