Reaction Steps

A mixture of 6-(3-chloro-4-fluorobenzyl)-4-hydroxy-N,N-dimethyl-2-isopropyl-3,5-dioxo-2,3,5,6,7,8-hexahydro-2,6-naphthyridine-1-carboxamide (95 mg, 0.22 mmol; Example 13) and 10% palladium on charcoal (0.11 g) in methanol (5 mL) was stirred under a balloon of hydrogen gas at room temperature overnight. The reaction mixture was filtered, and the filtrate concentrated under vacuum. The residue was subjected to preparative HPLC purification on C-18 reverse stationary phase column eluting with a gradient of water—acetonitrile in the presence of 0.1% trifluoroacetic acid. Collection and lyophilization of appropriate fractions provided the titled compound.
