反応手順
Following method 11, tert-butyl 1-(2-amino-4-methoxyphenyl)piperidin-4-ylcarbamate was coupled to 3-amino-6-bromopyrazine-2-carboxylic acid with TEA (3 eq) in ACN at 55° C. for 48 hours. Concentrated, triturated in cold ACN, filtered, and dried in vacuo yielding tert-butyl 1-(2-(3-amino-6-bromopyrazine-2-carboxamido)-4-methoxyphenyl)piperidin-4-ylcarbamate (7%). LCMS (m/z): 521.1 (MH+); LC Rt=3.63 min.
