Reaction Steps

To a solution of (S)-5-(4-(3-(((4-amino-2,2-dioxido-1H-benzo[c][1,2,6]thiadiazin-5-yl)oxy)methyl)piperidin-1-yl)-2-methyl-4-oxobutan-2-yl)-2-methoxyphenyl methanesulfonate (200 mg, 0.34 mmol) (Example 50) in EtOH (20 mL) was added 2N aqueous NaOH (0.34 mL). The reaction mixture was stirred at 85° C. for 3 hours, cooled to 0° C. and neutralized 2N HCl. The solution was concentrated under reduced pressure and purified by preparative HPLC (10-90% acetonitrile in water) to give the title compound (78 mg, 45%). 1H NMR (400 MHz, DMSO-d6) δ 1.17-1.32 (m, 8H), 1.43-1.64 (m, 2H), 1.74-1.8 (m, 1H), 2.52-2.67 (m, 2H), 2.77-2.83 (m, 0.5H), 3.51-3.54 (m, 0.5H), 3.65-3.68 (m, 4H), 3.73-3.84 (m, 2H), 4.1-4.18 (m, 1H), 5.9-5.94 (m, 1H), 6.15-6.19 (m, 1H), 6.5 (brs, 1H), 6.66-6.78 (m, 3H), 6.89-6.95 (m, 1H), 8.71 (s, 1H). MS 517 (MH+).
