Product 1

HCID 545918432-{2-Fluoro-4-[4-((R)-2-methyl-pyrrolidin-1-yl)-cyclohexyl]-phenyl}-1-oxo-2,8-diaza-spiro[4.5]decane-8-carboxylic acid tert-butyl ester

Procedure

The title compound was synthesized in the same manner as Example 13 by condensing 2-[2-fluoro-4-(4-methanesulfonyloxy-cyclohexyl)-phenyl]-1-oxo-2,8-diaza-spiro[4.5]decane-8-carboxylic acid tert-butyl ester (Intermediate 28) (150 mg, 0.3 mmol, 1 equiv.) with (R)-2-methyl-pyrrolidine (101.2 mg, 1.19 mmol) to obtain 45 mg (67% yield) of the compound.
