Procedure

A mixture of 10-(3-chloro-4-fluorobenzyl)-8-hydroxy-2-(4-methoxybenzyl)-2,3,4,5,11,12-hexahydro[1,4]diazepino[2,1-a]-2,6-naphthyridine-1,7,9(10H)-trione (18 mg, 30 μmol) and p-toluenesulfonic acid (26 mg, 0.14 mmol) in toluene (0.5 mL) was heated at 110° C. for 8 hours. The reaction mixture was concentrated under vacuum. The residue was purified by reverse phase high pressure liquid chromatography. Collection and lyophilization of appropriate fractions provided the title compound.
