Reaction Steps

2-(2-(4-(5-(3-phenoxy-5-(pyridin-2-ylthio)pyridin-2-ylamino)-1,2,4-thiadiazol-3-yl)piperidin-1-ylsulfonyl)ethyl)isoindoline-1,3-dione (0.110 g, 0.157 mmol) and hydrazine monohydrate (0.0236 g, 0.472 mmol) were dissolved in EtOH (25 mL) and heated to reflux for 8 hours. The reaction was cooled to ambient temperature and the solids filtered and triturated with EtOH to afford the title compound (0.013 g, 14.5% yield). 1H NMR (d6-DMSO) δ 8.38 (d, 1H), 8.36 (m, 1H), 7.66 (dt, 1H), 7.45 (d, 1H), 7.41 (t, 2H), 7.20-7.10 (m, 5H), 3.61 (d, 2H), 3.12 (t, 2H), 3.01-2.89 (m, 5H), 2.09 (d, 2H), 1.79 (m, 2H).
