Reaction Steps

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 5-acetyl-2-thiopheneboronic acid (26.32 mg; 0.15 mmol; 1.10 eq.) instead of 4-fluorophenylboronic acid and was obtained as a yellow solid (15 mg, 26%). (HPLC (method F): 88%, RT: 3.84 min); 1H NMR (500 MHz, DMSO-d6) δ [ppm] 8.56 (d, J=5.1, 1H), 8.22 (d, J=4.0, 1H), 8.12 (d, J=3.8, 1H), 7.79 (d, J=1.0, 1H), 7.78 (d, J=5.1, 1H), 7.40 (s, 2H), 3.94 (s, 6H), 3.76 (d, J=0.9, 3H), 2.63 (s, 3H); MS (m/z) 410 [M+H]+, RT: 2.5 min.
