Procedure
Cesium carbonate (117.3 mg, 0.36 mmol) was added to 4-chloroimidazo[4,5-c]pyridine (25 mg, 0.18 mmol) in DMF (2 mL) at room temperature under nitrogen. After stirring for 15 min, a solution of 4-(1-carbomethoxy- 1-(3,4-methylenedioxyphenyl)methoxy)-3,5-dipropylbenzyl bromide (106.5 mg, 0.23 mmol) in DMF (2 mL) was added and the mixture stirred at room temperature for 12 h. The mixture was poured onto ice/water and the crude product that precipitated was collected by filtration. The crude material was pre-adsorbed on silica gel and chromatographed (0 to 50% hexane/ethyl acetate) to afford the title compound (25 mg).
