Reaction Steps

A 100 mL flask was charged with 7-[5-(4-fluorobenzyl)-4H-1,2,4-triazol-3-yl]-5-thiomorpholin-4-yl-1,6-naphthyridin-8-ol (26 mg, 0.062 mmol). Methanol (15 mL) and chloroform (˜3 mL to dissolve insoluble solids) were added, followed by a freshly prepared 0.16 M solution of Oxone (0.75 mL, 0.12 mmol) in methanol. The solution was stirred for 14 hours at room temperature. The reaction mixture was concentrated in vacuo, diluted with dichloromethane and extracted twice. The combined organics were concentrated in vacuo and purified by preparative HPLC. Thus, 5-(1,1-dioxidothiomorpholin-4-yl)-7-[5-(4-fluorobenzyl)-4H-1,2,4-triazol-3-yl]-1,6-naphthyridin-8-ol (7.3 mg, 26%) was prepared as a tan solid. 1H NMR (CD3OD/CDCl3): δ 8.99 (dd, J=4.4, 1.6 Hz, 1 H), 8.31 (dd, J=8.4, 1.6 Hz, 1 H), 7.52 (dd, J=8.4, 4.4 Hz, 1 H), 7.24 (m, 2 H), 6.91 (m, 2 H), 4.08 (s, 2 H), 3.85 (m, 4 H), 3.25 (m, 4 H); MS m/z 455 (M+1).
