Participants

Reaction Steps

The title compound was prepared according to the method of Example 6 starting with 2-(4-fluorophenyl)-4-methoxy-5-bromo-3(2H)-pyridazinone in place of 2-benzyl-4-bromo-5-methoxy-3(2H)-pyridazinone and substituting 4-(methylthio)benzeneboronic acid in place of 4-fluorobenzeneboronic acid (yield: 70 mg, 61%). 1H NMR (500 MHz, DMSO-d6) δ 2.54 (s, 3H), 4.02 (s, 3H), 7.35 (dd, J=9.0, 9.0 Hz, 2H), 7.39 (d, J=8.5 Hz, 2H), 7.61 (d, J=8.5 Hz, 2H), 7.65 (dd, J=9.0, 5.0 Hz, 2H), 8.14 (s, 1H). MS (APCI+) m/z 343 (M+H)+.
