Reaction Steps

Following the procedure described above for compound 236 (step 4, example 95, scheme 63) but replacing amine 239 with 7-(4-amino-2-fluorophenoxy)-N,N′,N′-trimethylthieno[3,2-b]pyridine-2-carbohydrazide (244), title compound 241 was obtained in 43% yield. 1H NMR (400 MHz, DMSO-d6) δ (ppm): 10.45 (s, 1H), 8.45 (d, J=5.4 Hz, 1H), 7.79 (d, J=13.3 Hz, 1H), 7.67 (s, 1H), 7.62-7.31 (m, 7H), 6.62 (d, J=5.4 Hz, 1H), 3.40 (s, 9H), 3.23 (s, 2H), 3.21 (s, 3H). MS (m/z): (M+1) 536.2 (100%).
