Reaction Steps

The product of Step 1 (1.25 g, 4.8 mmol) is dissolved into EtOAc (30 mL) in a Parr bottle and 10% Pd/C (100 mg) added under nitrogen. The mixture is hydrogenated on a Parr apparatus for 4 hrs at 40 psi. Filtration and evaporation of solvent gave a solid (1.1 g, 99%). Mp 119-21° C. HRMS (FAB) calcd for C9H11FN2O2S +H1 231.0603, found 231.0610.
