Versuchsvorschrift

A mixture of 5-(4-methylsulfonyl-phenyl)-dispiro[2,3-dihydrofuro[2,3-c]pyridine-2,1′-cyclobutane-3′,4″-piperidine] (HCl salt; 50 mg), 2-chloro-5-ethyl-pyrimidine (18 mg), potassium carbonate (35 mg), and N-methyl-pyrrolidinone (2 ml) is stirred at 80° C. for 4 h. After cooling to room temperature, water is added and the resulting mixture is extracted with ethyl acetate. The combined extracts are dried (Na2SO4) and concentrated. The residue is chromatographed on silica gel (cyclohexane/ethyl acetate 1:1→1:9) to give the title compound. LC (method 1): tR=1.16 min; Mass spectrum (ESI+): m/z=491 [M+H]+.
