Reaction Steps

To a solution of 1,1-dimethylethyl {1-[2-(8-ethyl-7-fluoro-2-oxo-1,5-naphthyridin-1(2H)-yl)ethyl]-4-piperidinyl}carbamate (0.234 g, 0.559 mmol) in DCM (2 ml) was added TFA (1 ml) and the reaction was allowed to stirred at rt for 1 h before evaporation of solvent. The residue was dissolved in 1:1 DCM and MeOH (2 ml) and then treated with MP-Carbonate resin until the pH reached 8. The reaction was then filtered, resin washed with MeOH and the filtrate was evaporated to dryness to give a yellow oil (0.176 g, 99%).
