Procedure

A mixture of (5-benzenesulfinylmethyl-pyrrolo[2,1-f][1,2,4]triazin-4-yl)-[1-(3-fluoro-benzyl)-1H-indazol-5-yl]-amine (100 mg, 0.20 mmole) and (3R)-3-(N-tert-butoxycarbonylamino)pyrrolidine; (380 mg, 10 equiv) in a sealed tube was heated at 130° C. for 35 hr. The reaction mixture was taken up in DCM, washed water and dried (Na2SO4). After removal of the solvent the residue was taken up in DCM (1.5 mL) and TFA (1 mL) was added. The solvents were removed and the residue was dissolved in DCM, washed with water, and dried (Na2SO4). Removal of the solvent followed by radial chromatography (2 mm silica gel plate employing gradient elution with DCM containing 1 to 5% MeOH) to afforded the title compound as an oil (13 mg, 14%). 1H NMR (CDCl3) δ 1.49 (br s, 2H), 1.66 (m, 1H), 2.29 (m, 1H), 2.43 (m, 1H), 3.69 (m, 1H), 3.87 (d, 1H, J=13.5 Hz), 3.96 (d, 1H, J=13.5 Hz), 5.58 (s, 2H), 6.49 (d, 1H, J=3 Hz), 6.8-7.6 (m, 7H), 7.92 (s, 1H), 8.04 (s, 1H), 8.26 (d, 1H, J=2 Hz); MS: 457 (M+H)+; HPLC Ret Time: 1.15 min (YMC Xterra ODS S7 C18, 3.0×50 mm column, 2 min gradient, 5 mL/min).
