実験手順

1-Methyl-cyclopropyl 4-nitrophenyl carbonate (48 mg) is added to a solution of 5-(2-fluoro-4-methanesulfonyl-phenyl)-2-piperidin-4-yl-furo[2,3-c]pyridine (75 mg) and N,N-diisopropyl-ethylamine (32 μL) in tetrahydrofuran (1 mL) at room temperature. The mixture is stirred at room temperature overnight. The solution is concentrated and the residue is taken up in ethyl acetate. The resulting mixture is washed with 1 M aqueous NaOH solution (3×), water, and brine. The organic phase is dried (Na2SO4) and concentrated. The residue is purified by HPLC on reversed phase (methanol/water) to give the title compound. Mass spectrum (ESI+): m/z=473 [M+H]+.
