1-(benzoyl)-4-[(4-methoxy-7-(2-amino-pyrazin-5-yl)-6-azaindol-3-yl)-oxoacetyl]piperazine (4 mg) and acetic anhydride (20 mg) were dissolved in pyridine (0.5 ml). The reaction was stirred for three hours at room temperature. After reaction was quenched with MeOH (1 ml), solvents were concentrated to give a residue which was purified using a Shimadzu automated preparative HPLC System to provide 3.0 mg of the desired compound, 1-(benzoyl)-4-[(4-methoxy-7-(2-acetylamino-pyrazin-5-yl)-6-azaindol-3-yl)-oxoacetyl]piperazine. 1H NMR (500 MHz, CD3OD) δ9.58 (s, 1H), 9.25 (s, 1H), 8.45 (s, 1H), 8.10 (s, 1H), 7.49 (m, 5H), 4.12 (s, 3H), 3.84-3.35 (m, 8H), 2.27 (s, 3H). MS m/z: (M+H)+ Calc'd for C27H26N7O5: 528.20; found 528.22. HPLC retention time: 1.33 minutes (column A).
