実験手順

A mixture of (2-isopropylthiazol-4-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone trifluoroacetate (example 22, step b) (0.85 g) and 2-(3-(bromomethyl)phenyl)ethanol (example 6, step a) (0.432 g) in acetonitrile (10 mL) at 20° C. was treated with triethylamine (0.616 mL) and then stirred for 2 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, elution gradient 1% triethylamine and 3% methanol in dichloromethane. Pure fractions were evaporated to dryness to afford the subtitled compound. Yield 0.71 g.
