Abstract
In the present study, the substituted 3-(4-chlorophenyl)-N-(ptolyl)
acrylamide(1)was first prepared via Claisen-Schmidt condensation reaction of
N-(p-tolyl)acetamide with P-chlorobenzaldehyde in ethanol and NaOH solution
(20%) [c.f. (Scheme 1)]. The reaction of 3-(4-chlorophenyl)-N-(p-tolyl)acrylamide(1) with urea in
ethanol at reflux temperature in the presence of sodium ethoxide gave 4-(4-
chlorophenyl)-6-(p-tolylamino)pyrimidin-2-ol (2) in 76 % yield (Scheme 2).
On the other hand, 4-(4-chlorophenyl)-6-(p-tolylamino)pyrimidine-2(5H)-
thione (3) was formed in 76 % yield by the reaction of 3-(4-chlorophenyl)-N-(ptolyl)
acrylamide (1) with thiourea in ethanolic KOH solution at reflux temperature
(Scheme 2).
