Procedure
A mixture of 1-[(2S,3R)-2-hydroxy-5-(2-hydroxyphenyl)-3-pentyl]imidazole-4-carboxamide (obtained in Example 23(4)) (4.1 mg), 1-bromo-3-phenylpropane (7 mg), and potassium carbonate (4 mg) in N,N-dimethylformamide (0.5 ml) was stirred overnight at room temperature. The mixture was taken up in ethyl acetate, washed twice with water, dried, and evaporated. The residue was purified by column chromatography on silica gel, eluting with a mixture of dichloromethane and methanol (20:1) to give a colorless gummy oil of 1-{(2S,3R)-2-hydroxy-5-[2-(3-phenylpropoxy)phenyl]-3-pentyl}imidazole-4-carboxamide (4.9 mg).
