実験手順

To a solution of 2-Butyl-5-hydroxy-4-(7-hydroxy-1,1-dioxo-1,2-dihydro-1λ6-benzo[1,2,4]thiadiazin-3-yl)-6-isopropyl-2H-pyridazin-3-one (5f) (38.7 mg, 95.2 μmol) in anhydrous DMF (4 mL), 2-Bromo-acetamide (14.5 mg, 104.7 μmol) was added followed by K2CO3 (39.5 mg, 285.6 μmol). The resulted mixture was heated at 80° C. overnight with stirring. The reaction mixture was concentrated under reduced vacuum and the residue was purified by flash chromatography on silica gel to give the desired product (5g) (21.7 mg) in 49.2% yield. 1H NMR (400 MHz, DMSO-d6): δ7.63-7.66 (m, 1H), 7.62 (br, 1 H), 7.40 (br, 1H), 7.34-7.39 (m, 2 H), 4.58 (s, 2H), 4.10 (m, 2H), 3.23 (m, 1H, J=6.8 Hz), 1.72 (m, 2H, J=7.2 Hz), 1.32 (m, 2H. J=7.2 Hz), 1.21 (d, 6H, J=6.4 Hz), 0.91 (t, 3H, J=7.2 Hz); LC-MS (ESI+): m/e=464.1-[M+1]+ (exact MS: 463.15).
