Reaktionsschritte

Following method 11, tert-butyl 4-(2-amino-4-benzoylphenyl)piperazine-1-carboxylate was coupled to 3-amino-6-bromopyrazine-2-carboxylic acid with TEA (1.5 eq) in ACN at 55° C. for 48 hours. Concentrated, triturated in cold ACN, filtered, and dried in vacuo yielding tert-butyl 4-(2-(3-amino-6-bromopyrazine-2-carboxamido)-4-benzoylphenyl)piperazine-1-carboxylate (50%). LCMS (m/z): 581.1 (MH+); LC Rt=4.00 min.
