Reaction Steps
This compound was prepared in a manner analogous to that of Step C of Example 3, using 1.3 grams (0.005 mole) of 2,4-diamino-5-iodo-6-methylpyrimidine, 1.6 grams of (0.008 mole) of 3-methyl-3-(4-trifluoromethylphenyl)-1-butyne (prepared as in Step F of Example 17), 0.3 gram of bis(triphenylphosphine)palladium(II) chloride, 0.05 gram of copper iodide, and 8 mL of piperidine in 20 mL of N,N-dimethylformamide, yielding 1.6 grams of 2,4-diamino-6-methyl-5-[3-(4-trifluoromethylphenyl)-3-methyl-1-butynyl]pyrimidine, mp 153°-157° C. The NMR spectrum is consistent with the proposed structure.
