Pyrimethamine synthesis

5synthesis methods
Pyrimethamine, 2,4-diamino-5-(4-chlorophenyl)-6-ethylpyrimidine (33.1.60), is synthesized from 4-chlorobenzycyanide, which upon condensation with methyl ester of propionic acid in the presence of sodium methoxide gives the β-ketonitrile (33.1.58). Reacting this with ethyl orthoformate gives a methoxymethylene derivative (33.1.59), which upon heterocyclization in pyrimidine using guanidine as the binucleophile forms the desired pyrimethamine (33.1.60).
