Procedure
A solution of 3-[bis(methylthio)methylene]-1-[(cyclopropylmethyl)amino] quinoline-2,4(1H,3H)-dione (500.3, 1.5 mmol) and the product of 2-amino-4-[(methoxymethoxy)methyl]thiophene-3-sulfonamide (377.62 mg, 1.5 mmol) in dioxane (15 mL) was stirred at reflux for 1.5 hours and concentrated under reduced pressure. The residue was purified by chromatography on silica gel eluting with 0% to 10% ethyl acetate/dichloromethane to give 1-[(cyclopropylmethyl)amino]-4-hydroxy-3-{7-[(methoxymethoxy)methyl]-1,1-dioxido-4H-thieno[2,3-e][1,2,4]thiadiazin-3-yl}quinolin-2(1H)-one (384.7 mg, 52%). 1H NMR (300 MHz, DMSO-d6) δ 0.15 (m, 2 H) 0.42 (m, 2 H) 1.01 (m, 1 H) 2.84 (d, J=6.99 Hz, 2 H) 4.64 (s, 2 H) 4.71 (s, 2 H) 6.36 (br s, 1 H) 7.42 (m, 2 H) 7.86 (m, 1 H) 8.07 (d, J=8.46 Hz, 1 H) 8.16 (m, 1 H).
