The present invention relates to new derivatives selected from the group comprising: (i) the 5-phenylhydropyrimidines of the formula: ##STR1## in which: X.sub.1 and X.sub.2, which are identical or different, each represent H, F, Cl, Br or CF.sub.3, and A represents a polyhydropyrimidinyl group of the structure: ##STR2## in which: Y represents H or OH, R.sub.a represents a C.sub.1 -C.sub.4 alkyl group or a C.sub.2 -C.sub.5 alkanoyl group, it being possible for R.sub.a to represent the hydrogen atom when at least one of the groups X.sub.1, X.sub.2 and Y is different from H, R.sub.b represents a C.sub.1 -C.sub.3 alkyl group, and R.sub.c.sup.1 and R.sub.c.sup.2, which are identical or different, each represent the hydrogen atom or a C.sub.1 -C.sub.3 alkyl group; and (ii) their addition salts. The said derivatives are useful as pharmaceuticals.
