HCID 219342552-(3-Chlorophenyl)-4-(2-methylpropoxy)-5-[4-(aminosulfonyl)phenyl]-3(2H)-pyridazinone

Procedure

The title compound was prepared according to the method of Example 384, substituting 2-(3-chlorophenyl)-4-(2-methylpropoxy)-5-[4-(methylsulfonyl)phenyl]-3(2H)-pyridazinone (Example 335) in place of 2-benzyl-4-(4-fluorophenyl)-5-[4-(methylsulfonyl)phenyl]-3(2H)-pyridazinone (yield: 0.0458 g, 25%). mp 80-85° C. 1H NMR (300 MHz, DMSO d6) δ 0.80 (d, J=6 Hz, 6H), 1.74-1.92 (m, 3H), 4.20 (d, J=6 Hz, 2H), 7.49-7.64 (m, 5H), 7.76 (m, 1H), 7.85 (m, 2H), 7.95 (m, 2H), 8.21 (m, 1H). MS (DCI/NH3) m/z 434 (M+H)+, 451 (M+NH4)+. Anal. calc. for C20H20ClN3O4S: C, 55.36; H, 4.65; N, 9.68. Found: C, 55.12; H, 4.58; N, 9.42.
