N-hydroxyethylpiperazine (7.81 g.) diluted with 20 ml. of absolute ethanol is added to a slurry obtained by adding 6.75 g. of 4,6-dichloro-2-phenylpyrimidine to 25 ml. of absolute ethanol. The resulting mixture is refluxed for fifteen minutes, then poured into 850 ml. of water. A gummy material which separates solidifies on standing overnight. The crude product weighs 7.8 g. which is recrystallized from n-heptane to afford 4-(4-chloro-2-phenylpyrimidin-6-yl)-1-piperazineethanol, m.p. 103°-105°C.
