6-(morpholin-4-yl)-4-(2-naphthyl)-2-{[2-(trimethylsilyl)ethoxy]methyl}-3,4-dihydro-2H-thieno[3,2-e][1,2]thiazin-4-ol 1,1-dioxide (0.030 g, 0.055 mmol) was dissolved in THF (2.0 mL) and 1.00 M tetra-n-butylammonium fluoride in THF (0.549 mL, 0.549 mmol) was added. The solution was stirred at 40° C. overnight. The solvent was evaporated and the residue was purified using silica gel chromatography (12 g silica gel column, gradient 20% EA in hexane to 100% EA over 15 minutes) to give the product (14 mg, 55%). LCMS (FA) ES+: 417. 1H NMR (400 MHz, CD3OD) δ 7.94 (s, 1H), 7.86-7.83 (m, 3H), 7.50-7.47 (m, 2H), 7.39-7.36 (m, 1H), 5.66 (s, 1H), 5.48 (s, 1H), 3.96 (d, 1H), 3.73-3.70 (m, 4H), 3.62 (d, 1H), 3.09-3.05 (m, 4H).
