Procedure

To a suspension of (S)-1-(3-(((4-amino-2,2-dioxido-1H-benzo[c][1,2,6]thiadiazin-5-yl)oxy)methyl)piperidin-1-yl)-3-methylbutan-1-one (2.0 g, 5.07 mmol) (Example 5) in water (25 mL), was added NaHCO3 (425 mg, 5.07 mmol). The reaction was heated to reflux until complete dissolution of solid material occurred, and then concentrated under reduced pressure. The resulting residue was dissolved in water and lyophilized to give the title compound as a beige solid (2.1 g, 100%). 1H NMR (400 MHz, DMSO-d6) δ 0.78-0.96 (m, 6H), 1.21-1.50 (m, 2H), 1.55-1.75 (m, 1H), 1.78-2.07 (m, 3H), 2.10-2.25 (m, 2H), 2.60-2.78 (m, 1H), 2.88-3.15 (m, 2H), 3.65-3.97 (m, 3H), 4.00-4.41 (m, 1H), 5.97 (t, 1H, J=8.0 Hz), 6.21 (d, 1H, J=8.8 Hz), 6.57 (br. s, 2H), 6.95 (d, 1H, J=8.0, 3.2 Hz). MS 395 (MH+—Na).
