Participants

Reaction Steps

1-(2-Pyrrolidin-1-yl-ethyl)-1H-indazol-4-ylamine (1.00 g, 4.34 mmol), tert-butoxycarbonylamino-acetic acid (0.836 g, 4.77 mmol), ethyldimethylpropylcarbodiimide hydrochloride (1.00 g, 5.24 mmol), N-hydroxybenzotriazole (0.707 g, 5.24 mmol) and N-methyl morpholine (1.10 g, 10.9 mmol) were dissolved in 30 mL of DMF, and stirred at room temperature for 6 hours. The mixture was concentrated under reduced pressure and the residue purified by flash chromatography to provide the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 1.41 (s, 9H), 1.62 (m, 4H), 2.44 (m, 4H), 2.86 (t, 2H, J=6.78), 3.86 (d, 2H, J=6.11), 4.47 (t, 2H, J=6.78), 7.08–7.65 (m, 4H), 8.24 (s, 1H), 9.97 (s, 1H); MS (DCI/NH3) m/z 388 [M+H]+.
