反応手順
To a solution of 3-amino-N-(4-(3-aminopiperidin-1-yl)pyridin-3-yl)-6-bromopyrazine-2-carboxamide in CH2Cl2 at room temperature was added 1-methylpiperidin-4-one (1.5 eq) followed by sodium triacetoxyborohydride (5.0 eq). The reaction was stirred at room temperature for 12 hours, concentrated, purified by reverse phase HPLC and lyophilized to provide 3-amino-6-bromo-N-(4-(3-(1-methylpiperidin-4-ylamino)piperidin-1-yl)pyridin-3-yl)pyrazine-2-carboxamide, (66%). LCMS (m/z): 489.2 (MH+).
