Versuchsvorschrift

To a solution of (R)-6-(3-aminopiperidin-1-yl)-2-(4-(morpholine-4-carbonyl)phenylamino)nicotinamide (30 mg, 0.071 mmol) and Et3N (0.049 mL, 0.353 mmol) in THF (2 mL) was added benzenesulfonyl chloride (18.72 mg, 0.106 mmol). The solution was stirred at rt for 10 min. The reaction mixture was diluted with CH2Cl2, washed with satd NaHCO3, separated, and concentrated. The residue was purified (ISCO, 5% NH4OH/MeOH/CH2Cl2, 40 g silica gel column) to obtain 30 mg of (R)-2-(4-(morpholine-4-carbonyl)phenylamino)-6-(3-(phenylsulfonamido)piperidin-1-yl)nicotinamide as a light yellow solid. LCMS: (M+H)+=465.40. 1H NMR (400 MHz, CDCl3) δ ppm 11.13 (1H, s), 7.84-7.90 (2 H, m), 7.58-7.63 (2H, m), 7.54-7.57 (1H, m), 7.44-7.52 (3H, m), 7.33 (2H, d, J=8.56 Hz), 5.99 (1H, d, J=8.81 Hz), 5.71-5.87 (2H, m), 3.85 (1H, d, J=10.83 Hz), 3.38-3.79 (12H, m), 1.67-1.79 (2H, m), 1.44-1.57 (2H, m).
