Reaction Steps

A solution of 2-azido-1-(5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinolin-1-yl)-ethanone (4.70 g, 19.58 mmol), (BOC)2O (4.48 g, 20.56 mmol), Pd/C (10%) in THF (30 mL)/MeOH (20 mL) was shaken under H2 (60 psi) overnight. The mixture was filtered through a pad of Celite and concentrated to give a residue that was purified by silica gel column chromatography (eluent, 2/1 hex/EtOAc). [2-(5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinolin-1-yl)-2-oxo-ethyl]-carbamic acid tert-butyl ester was obtained as a white solid (2.82 g, 46%). M.p.=175-177° C.; 1H NMR (400 MHz, DMSO-d6) δ: 8.35 (s, 1H), 7.86 (d, J=8.0 Hz, 1H), 7.12 (t, J=7.6 Hz, 1H), 6.99 (m, 2H), 4.27 (d, J=6.0 Hz, 2H), 4.23 (t, J=6.0 Hz, 2H), 2.94 (t, J=6.4 Hz, 2H), 2.14 (m, 2H), 1.41 (s, 9H). LCMS: m/e 315.21 [M+H], 259.17 [M-56].
