실험 절차

To a solution of (R)-6-(3-aminopiperidin-1-yl)-2-(4-(morpholine-4-carbonyl)phenylamino)nicotinamide (35 mg, 0.082 mmol) in THF (2 mL) was added 2-isocyanatopropane (14.03 mg, 0.165 mmol) and 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 obtained 30.2 mg of (R)-6-(3-(3-isopropylureido) piperidin-1-yl)-2-(4-(morpholine-4-carbonyl)phenylamino)nicotinamide as a light yellow solid.
