Reaction Steps

A mixture of 4,5-dihydro-1H-pyrrolo[2,3-f]isoquinoline-3-carboxylic acid E6 (0.093 mmol), HOBT.NH3 (0.374 mmol), TBTU (0.186 mmol) and DIEA (0.374 mmol) in DMF (5 mL) was stirred 4 h at rt. The solvent was evaporated and the crude residue was purified by preparative HPLC (Phase A: 0.05% NH4OH pH10/AN 95/5, Phase B: AN; gradient phase B 0—50% 8 min, yield 30%). ESI (+) MS: m/z 214 (MH+). 1H NMR: 2.83 (t, J=7.93, 2H), 2.98 (t, J=8.05, 2H), 6.61-7.28 (m, 2H), 7.33 (d, J=5.00, 1H), 7.56 (d, J=2.80, 1H), 8.28-8.38 (m, 2H), 11.85 (bs, 1H).
