Reaction Steps

piperazine (7.54 g, 87.57 mmol) was dissolved in EtOH, 2-tert-butyl-4-chloro-6-cyclobutyl-pyrimidine (3.28 g, 14.60 mmol) was added dropwise at 80° C. over 10 min The solution was refluxed overnight and then concentrated under reduced pressure. The residue was dissolved in EtOAc, washed with water and brine, dried over Na2SO4, filtered, and concentrated under reduced pressure to give the title compound (3.5 g, 87%).
