Procedure
To a solution of 3-bromo-5-methoxy-α,α-dimethyl-4-[[6-chloro-2-methyl-5-nitro-4-pyrimidinyl]oxy]benzenemethanol (1.88 g) in anhydrous 1,4-dioxane (50 mL) with 0.50 g of potassium carbonate, 4-heptylamine (1.00 mL) was added and the solution was stirred at room temperature for 2 hours. The solvent was removed under reduced pressure and the residue was taken up in water and extracted with methylene chloride. The extracts were combined and dried over MgSO4. The solvent was removed under reduced pressure and the residue was purified by chromatography on silica gel using a 1:1 mixture of ethyl acetate and hexane to yield the title compound, mp 138° C.
