Versuchsvorschrift

2-(3-(Bromomethyl)phenyl)ethanol (example 6, step a) (0.281 g) was added to a solution of (5-methylthiophen-2-yl)(5-oxa-2,8-diazaspiro[3.5]nonan-8-yl)methanone hydrochloride (example 33, step h) (0.29 g) and triethylamine (0.42 mL) in acetonitrile (15 mL) at 20° C. and the resultant mixture stirred for 3 hours at 20° C. The solvent was removed under reduced pressure and the residue partitioned between ethyl acetate and brine. The organic layer was dried over sodium sulphate, filtered and the solvent removed under reduced pressure. The crude product was purified by flash silica chromatography using 3% methanol in dichloromethane with 1% triethylamine as solvent. Pure fractions were evaporated to dryness to afford the subtitled compound. Yield 0.32 g.
