To a suspension of 2-(4-(morpholine-4-carbonyl)phenylamino)-6-(piperazin-1-yl)nicotinamide (28 mg, 0.068 mmol) and Et3N (0.019 mL, 0.136 mmol) in THF (2 mL) and CH2Cl2 (2.000 mL) was added 2-phenylacetyl chloride (10.55 mg, 0.068 mmol). The reaction mixture was stirred at rt for 10 min, diluted with CH2Cl2, washed with satd NaHCO3, separated, and concentrated. The residue was purified by prep-HPLC. The product containing fractions were collected, basified with 1N NaOH, extracted with CH2Cl2, separated, and concentrated to give 14 mg of 2-(4-(morpholine-4-carbonyl)phenylamino)-6-(4-(2-phenylacetyl)piperazin-1-yl)nicotinamide as a white solid. LCMS: (M+H)+=529.40. 1H NMR (400 MHz, CDCl3) δ ppm 11.17 (1H, s), 7.63 (2H, d, J=8.56 Hz), 7.55 (1H, d, J=8.81 Hz), 7.35-7.40 (2H, m), 7.31-7.35 (2H, m), 7.23-7.31 (3H, m), 5.99 (1H, d, J=8.81 Hz), 5.59 (2H, s), 3.50-3.81 (18H, m).
