A mixture of 11-(3-chloro-4-fluorobenzyl)-9-methoxy-2-[2-(benzyloxy)ethyl]-3,4,5,6,12,13-hexahydro-2H[1,4]diazocino[2,1-a]-2,6-naphthyridine-1,8,10(1H)-trione (0.55 g, 0.97 mmol) and 5% rhodium on carbon (1.10 g) in ethyl acetate (22 mL) was stirred under a balloon of hydrogen at room temperature overnight. The product mixture was filtered through a pad of Celite. The filtrate was concentrated under vacuum to afford the title compound. This material was used in the following reaction without further purification.
