Reaction Steps

A mixture of (4-(methylsulfonyl)phenyl)hydrazine hydrochloride (1105 mg, 5.0 mmol; Acros), 1-azabicyclo[3.2.2]nonan-4-one (696 mg, 5.0 mmol; Example 2A), 4 N HCl in dioxane (2.5 mL, 10.0 mmol; Aldrich), and acetic acid (15 mL) was heated to 80° C. overnight (16 hours), then cooled to room temperature. The solvent was removed, and the residue was basified with 5 N sodium hydroxide and extracted with ethyl acetate (3×50 mL). The combined organic phases were concentrated in vacuo and purified by reverse-phase HPLC [Waters XBridge RP18 column, 5 μm, 30×100 mm, flow rate 40 mL/minute, 20-99% gradient of methanol in buffer (0.1 M aqueous ammonium bicarbonate, adjusted to pH 10 with ammonium hydroxide) over 20 minutes] to afford the title compound: 1H NMR (300 MHz, methanol-d4) δ ppm 2.05-2.14 (m, 4H), 3.02-3.15 (m, 6H), 3.20-3.28 (m, 2H), 4.29 (s, 2H), 7.47 (d, J=8 Hz, 1H), 7.57-7.62 (m, 1H), 7.95 (d, J=1 Hz, 1H); MS (DCI/NH3) m/z 291 (M+H)+.
