0.126M Sulfuric acid/THF (8.01 mL, 1.01 mmol) solution was added to a solution of cis-3-(((5R)-5-((7-fluoro-1,1-dimethyl-2,3-dihydro-1H-inden-5-yl)carbamoyl)-2-methoxy-7,8-dihydro-1,6-naphthyridin-6(5H)-yl)carbonyl)cyclobutanecarboxylic acid (500 mg, 1.01 mmol) in THF (10 mL) at room temperature. The mixture was concentrated under reduced pressure to dryness, and the solid was collected by filtration with ethyl acetate (10 mL) to give the title compound (548.3 mg, 0.924 mmol, 92%) as a white solid.
