実験手順

A mixture of (2-isopropylthiazol-4-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone hydrochloride [Example 27, step a] (10 g) and 2-(3-(2-bromoethyl)phenyl)ethanol [Organometallics 2002, 21(20), 4217] (10 g) and potassium carbonate (16 g) in acetonitrile (600 mL) and water (10 mL) was heated at 60° C. for 36 hours. The solvent was decanted off and evaporated under reduced pressure. The residue was partitioned between ethyl acetate and brine, the aqueous layer was re-extracted with ethyl acetate, and the combined organic layers were dried, filtered and the solvent evaporated under reduced pressure. The residue was purified by flash silica chromatography, using 5% methanol in ethyl acetate containing 1% triethylamine as solvent. Fractions containing the product were evaporated to dryness to afford the subtitled compound. Yield 11 g.
