Procedure

2-(3-Chlorophenyl)-4-(4-fluorophenyl)-5-[3-methyl-4-(methylthio)phenyl]-3(2H)-pyridazinone, was prepared according to the method of Example 228, starting with 2-(3-chlorophenyl)-4-methoxy-5-[3-methyl-4-(methylthio)phenyl]-3(2H)-pyridazinone in place of 2-(4-fluorophenyl)-4-methoxy-5-[4-(methylthio)phenyl]-3(2H)-pyridazinone and substituting 4-fluorophenyl magnesium bromide in place of cyclohexylmagnesium chloride (yield: 180 mg, 94%). 1H NMR (300 MHz, CDCl3) δ 2.25 (s, 3H), 2.56 (s, 3H), 7.28-7.45 (m, 6H), 7.58-7.63 (m, 1H), 7.71-7.74 (m, 1H), 7.82 (s, 1H). MS (APCI+) m/z 343 (M+H)+ and m/z 360 (M+NH4)+.
