Versuchsvorschrift

2-(3-(Bromomethyl)phenyl)ethanol (example 6, step a) (0.095 g) was added to a solution of (2,2-difluoro-1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)(5-methylthiophen-2-yl)methanone trifluoroacetate (example 37, step e) (0.19 g) and triethylamine (0.185 mL) in acetonitrile (10 mL) and the reaction mixture stirred at 20° C. for 3 hours. The solvent was evaporated under reduced pressure and the residue partitioned between ethyl acetate and brine, the organic layer was dried over sodium sulphate, filtered and the solvent evaporated under reduced pressure. The crude product was purified by flash silica chromatography using 2.5% methanol in dichloromethane with 1% triethylamine as solvent. Pure fractions were evaporated to dryness to afford the subtitled compound. Yield 0.188 g.
