実験手順

A mixture of 11-(3-chloro-4-fluorobenzyl)-9-hydroxy-2-methyl-4-pyrrolidin-1-yl-3,4,5,6,12,13-hexahydro-2H[1,4]diazocino[2,1-a]-2,6-naphthyridine-1,8,10(11H)-trione (40 mg, 0.08 mmol) and 33% hydrogen bromide in acetic acid (0.5 mL) in dioxane (1 mL) was stirred at room temperature for 1.5 hour. The product mixture was concentrated under vacuum. The residue was dissolved in DMSO and subjected to reverse phase column chromatography on C18 stationary phase eluted with a 95-5% water-acetonitrile gradient. Collection and Iyophilization of appropriate fractions afforded the title compound.
