Reaction Steps

A solution of [(R)-1-(4-Fluoro-benzyloxymethyl)-2-(2-methyl-1-oxo-4-phenyl-2,7-diaza-spiro[4.5]dec-7-yl)-2-oxo-ethyl]-carbamic acid tert-butyl ester (diastereomer 2 from step 1) (185 mg, 0.34 mmol) in DCM (4 ml) was treated with TFA (0.79 ml, 10.3 mmol). The resulting solution was stirred for 2 h at RT. The reaction mixture was diluted with DCM (20 ml) and quenched at 0° C. with 2M NaOH aqueous solution (10 ml). The organic phase was separated, washed with brine (5 ml), dried (MgSO4) and concentrated in vacuo to afford the title compound.
