Procedure

A mixture of 4-(4-bromophenyloxy)-1-trityl-1H-imidazole (0.345 g, 0.72 mmol) and the bromide from Example 1, Step 3 (0.19 g, 0.72 mmol) in anhydrous acetonitrile (10 mL) was heated under reflux at 60° C. for 24 h. The resultant solution was concentrated, and the residue dissolved in methanol. The methanolic solution was heated under reflux for 3 h, and concentrated under vacuum. The residue was subjected to column chromatography on silica gel eluting with 1:1 v/v 5% methanol in chloroform and chloroform saturated with ammonia gas. Collection and concentration of appropriate fractions provide the titled compound.
