Reaction Steps

A suspension of 0.1 mole of 4-amidino-benzoic acid ethyl ester hydrochloride, 0.1 mole of 2-n-heptyl-3-ethoxy-acrolein and 0.14 mole of sodium ethylate in 100 ml. of methanol is stirred overnight at room temperature under an atmosphere of nitrogen. After the usual work up and separation into basic and acidic fractions, there is obtained 4(4-n-heptylpyrimid-2-yl)-benzoic acid ethyl ester and 4-(4-n-heptylpyrimid-2-yl)-benzoic acid.
