Reaction Steps

To a solution of 6-oxo-N-[3-(1-trityl-1H-imidazol-4-yl)phenyl]-7,8,9,10-tetrahydro-6H-pyrido[3′,2′:4,5]pyrrolo[1,2-a][1,4]diazepine-2-carboxamide (86 mg, 0.14 mmol) in CH2Cl2 (1 mL) is added TFA (0.5 mL). The mixture is stirred at room temperature for 16 hr then is concentrated under reduced pressure. The residue is purified via preparative HPLC using a gradient elution from 10-75% acetonitrile/H2O with 0.1% TFA to afford the title compound (25 mg, 47%). LCMS: 387.86 (M+H+). (System T-med polar) Table 3 below, lists the mass spectral data and the HPLC retention times for Examples 1 to 105.
