Reaction Steps

Tert-butyl 2-chloropyrimidine-4-carboxylate (70 mg, 0.326 mmol) and (R)-3-methyl-1-(4-(methylsulfonyl)phenyl)piperazine (166 mg, 0.652 mmol) were dissolved in acetonitrile (2 ml), followed by addition of N,N-diisopropylethylamine (0.11 ml, 0.652 mmol), and then the resulting liquid was stirred at 100° C. under nitrogen stream for 24 hours. The resulting reaction liquid was concentrated under reduced pressure, and then the residue thus obtained was subjected to MPLC (50% EtOAc/Hexanes), to obtain 120 mg of pale yellow solid (85%).
