Reaction Steps

A mixture of 1-piperidin-4-yl-1,3-dihydro-benzimidazol-2-one (0.5 g, 2.3 mmol), 2-phenyl-ethylbromid (0.34 ml, 2.5 mmol), triethylamine (0.35 ml, 2.5 mmol) and sodium iodide (0.01 g, 0.67 mmol) in dry N,N-dimethyl foramide (5 ml) was stirred at 100° C. for 3 hours. The reaction mixture was cooled to room temperature, and then poured into water (20 ml). The product precipitated upon stirring on a ice/water bath and was isolated by filtration. Yield 0.45 g (1.4 mmol, 61%). M.p. 181-185° C.
