実験手順
A solution of methanesulfonic acid (1-trifluoromethyl-cyclopropyl)methyl ester (45 mg) and sodium iodide (34 mg) in N,N-dimethylformamide (2 mL) is stirred at room temperature for 4 h. 5-(4-Methylsulfonyl-phenyl)-dispiro[2,3-dihydrofuro[2,3-c]pyridine-2,1′-cyclobutane-3′,4″-piperidine] (HCl salt; 50 mg) and K2CO3 (35 mg) are added and the resulting mixture is heated to 60° C. After stirring the mixture at 60° C. for 4 h, water is added and the mixture is extracted with ethyl acetate. The combined extracts are dried (Na2SO4) and concentrated. The residue is triturated with methanol to give the title compound. LC (method 1): tR=0.82 min; Mass spectrum (ESI+): m/z=507 [M+H]+.
