Reaction Steps

A mixture of 1 g (7.7 mmol) 4-amino-6-chloropyrimidine (commercially available) and 1.75 g (15.4 mmol) 1-ethyl piperazine (commercially available) in 10 mL toluene was heated to 110° C. for 16 h. After evaporation of all volatiles the residue was purified by flash column chromatography on silica eluting with a gradient formed from DCM (0.5% NEt3) and methanol. The combined product fractions were evaporated to dryness to yield the title compound. MS (m/e): 208.3 (MH+).
