実験手順

Potassium carbonate (0.634 g) was added to a solution of (2-isopropylthiazol-4-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone trifluoroacetate [Example 1, step b] (0.971 g) and 4-(2-hydroxyethyl)phenethyl methanesulfonate [Aromatic Intermediate 10] (0.56 g) in acetonitrile (20 mL) and water (0.3 mL). The reaction mixture was heated at 60° C. for 1 day. The solvent was evaporated under reduced pressure and the residue partitioned between water and ethyl acetate. The aqueous layer was re-extracted with ethyl acetate and the combined organic phases were dried, filtered and the solvent evaporated under reduced pressure. The crude product was purified by flash silica chromatography, using 2% methanol in dichloromethane with 1% triethylamine as solvent. Fractions containing the product were evaporated to dryness to afford the subtitled compound. Yield 0.68 g.
