Reaction Steps

The previous amine, tert-Butyl 3-((5-cyclopropyl-3-(o-tolyl)isoxazol-4-yl)methoxy)-8-azabicyclo[3.2.1]octane-8-carboxylate (1.60 g, 3.65 mmol) was dissolved in trifluoroacetic acid in dichloromethane (30 mL, 20% solution) at RT. The solution was stirred for 1 hour at RT and the solvent was evaporated. The residue was dissolved in ethyl acetate (125 mL), washed with a saturated solution of sodium bicarbonate (100 mL), the organic layer was dried with magnesium sulfate and evaporated in vacuo. The crude residue was purified by silica gel chromatography using a gradient of 0-20% ethanol/dichloromethane to afford the desired product as a colorless oil. 1H-NMR (DMSO-d6, 400 MHz) δ 8.44 (bs, 1H), 7.43-7.34 (m, 2H), 7.32-7.28 (m, 2H), 4.21 (s, 2H), 3.83 (bs, 2H), 3.55 (t, J=4.0 Hz, 1H), 2.35-2.28 (m, 1H), 2.20 (s, 3Hc-1.70 (m, 8H), 1.16-1.06 (m, 4H). MS m/z 339.2 (M+1).
