Reaction Steps

Following the procedure used to prepare 3-[4-(1-amino-cyclobutyl)-phenyl]-6-fluoro-2-phenyl-chromen-4-one, {1-[4-(3-iodo-6-oxo-8-phenyl-1,6-dihydro-9-oxa-1,2-diaza-cyclopenta[a]naphthalen-7-yl)-phenyl]cyclobutyl}-carbamic acid tert-butyl ester was treated with TFA. The resultant free base was dissolved in a mixture of MeOH (2 mL), water (3 mL) and 1 M HCl (0.1 mL) and chromatographed on a 2 g C18 cartridge {gradient 40 to 80% MeOH in water+1 M HCl (60 μL in each 5 mL of eluent)} to give the title compound (2.1 mg, 56%) as a white solid.
