Reaction Steps

A mixture of the pyrimidine prepared in (a) above (24.5 g, 0.09 mole), piperazine (77.5 g, 0.9 mole), and toluene (160 mL) was heated at 150° C. in a stainless steel omb for 22 hr. The reaction mixture was filtered, concentrated in vacuo, and the residue crystallized from Skelly B to give 10.15 g (42%) off-white solid, m.p. 94°-97° C.
