Reaction Steps

To a stirred suspension of 2-(3-chlorophenyl)-4-tosyloxy-5-[4-(methylsulfonyl)phenyl]-3(2H)-pyridazinone, prepared in Example 333, (0.0802 g, 0.15 mmol) in EtOH (1.5 mL) was added thiocresol (0.019 g, 0.15 mmol) and K2CO3 (0.0203 g, 0.15 mmol). The suspension was heated to 50° C. with stirring for 2.5 hours. The mixture was poured into H2O with constant stirring. The resulting precipitate was filtered, rinsed with H2O and dried to provide the desired product (yield: 0.060 g, 83%). mp 178-178° C. 1H NMR (300 MHz, DMSO d6) δ 2.19 (s, 3H), 3.23 (s, 3H), 6.95 (m, 2H), 7.08 (m, 2H), 7.52-7.66 (m, 3H), 7.72 (m, 1H), 7.88 (m, 2H), 8.08 (s, 1H). MS (DCI/NH3) m/z 483 (M+H)+, 500 (M+NH4)+. Anal. calc. for: C24H19ClN2O3S2.0.75H2O: C, 58.05; H, 4.16; N, 5.64. Found: C, 57.99; H, 3.69; N, 5.76.
