Participants

Reaction Steps

This compound was prepared in a manner analogous to that of Example 2, Step E, using 0.8 gram (0.003 mole) of 1-ethoxy-2-cyano-5-(4-methoxyphenyl)-1-pentene, 1.3 grams (0.012 mole) of guanidine hydrochloride, and 2.7 grams (0.018 mole) of potassium carbonate in 15 mL of N,N-dimethylformamide. The yield of 1,4-diamino-5-[3-(4-methoxyphenyl)propyl]pyrimidine was 0.5 gram, mp 151°-154° C. The NMR spectrum was consistent with the proposed structure.
