実験手順

2-(4-Acetyl-phenyl)-8-(2-chloro-benzenesulfonyl)-2,8-diaza-spiro[4.5]decan-1-one (0.13 g), product of example 151), dissolved in THF (12 ml) under an argon atmosphere was treated at RT with (trifluoromethyl)trimethylsilane (0.062 g) then with tetra-n-butylammonium fluoride (1M solution in THF, 0.29 ml) and the reaction mixture was stirred overnight at RT. The mixture was made acidic with 3M aqueous HCl (a few drops) and stirred further 15 minutes. The solvent was removed in vacuo and the residue adsorbed on silica gel and chromatographed over silica gel (AcOEt/heptane, gradient from 0 to 40%) to give the desired product as white solid (0.091 g). MS (ESI): 517.1 MH+).
