Procedure

cis-(5-Bromo-thiophen-3-yl)-(octahydro-quinolin-1-yl)-methanone (0.15 mmol) was added to a solution of potassium carbonate (0.15 mmol), N,N′-dimethylethylene-diamine (0.03 mmol), imidazole (0.3 mmol) and copper (I) iodide (0.03 mmol) in DME (1 mL). The reaction mixture was heated under nitrogen to 120° C. for 90 hours and then diluted with DCM (5 mL) and washed with water. The organic solution was dried and filtered and the solvent evaporated. The residue was purified by HPLC, eluting with 10%-98% acetonitrile in water (0.1% formic acid) over 30 minutes. The fractions containing the desired product were concentrated under vacuum to give the title compound as a pale brown solid (26 mg). LCMS m/z 316.06 [M+H]+ RT=6.44 min. (Analytical Method 2).
