1-(3-bromopropoxy)-2-(trifluoromethyl)benzene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: This compound was prepared in a manner analogous to that of Step D of Example 12, using 2.4 grams (0.010 mole) of 2,4-diamino-5-hydroxy-6-methylpyrimidine hydrosulfate salt (prepared in Steps A-C of this Example), 3.0 grams (0.011 mole) of 2-trifluoromethylphenyl 3-bromopropyl ether, and 8.3 grams (0.060 mole) of finely ground potassium carbonate in 50 mL of N,N-dimethylformamide. The product was recrystallized from methanol and water, yielding 0.8 gram of 2,4-diamino-5-[3-(2-trifluoromethylphenoxy)propoxy]-6-methylpyrimidine, mp 132°-134° C. The NMR spectrum was consistent with the proposed structure. This compound was prepared in a manner analogous to that of Step D of Example 12 The product was recrystallized from methanol and water

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Under a nitrogen atmosphere, a stirred mixture of 4.0 grams (0.025 mole) of 2-trifluoromethylphenol, 17.8 mL (0.178 mole) of 1,3-dibromopropane, and 9.0 grams (0.065 mole) of potassium carbonate in 120 mL of acetone was heated at reflux for about 18 hours. After this time, the reaction mixture was concentrated under reduced pressure to a residual oil. The oil was subjected to column chromatography on silica gel. Elution was accomplished using petroleum ether. The product containing fractions were combined and concentrated under reduced pressure, yielding 5.9 grams of 2-trifluoromethylphenyl 3-bromopropyl ether. The NMR spectrum was consistent with the proposed structure. was heated at reflux for about 18 hours After this time, the reaction mixture was concentrated under reduced pressure to a residual oil Elution The product containing fractions concentrated under reduced pressure
