Triethylamine (0.18 mL) was added to a suspension of (2-isopropylthiazol-4-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone trifluoroacetate (example 22, step b) (0.217 g) and 2-(3-(bromomethyl)-5-chlorophenyl)ethanol (example 52, step b) (0.160 g) in acetonitrile (5 mL) and the resulting solution was stirred at room temperature overnight. The solution was then purified by flash chromatography on silica eluted with 1:5:94 triethylamine:methanol:dichloromethane to afford a gum. The gum was dissolved in dichloromethane and the solution was washed three times with water, dried over anhydrous magnesium sulphate and concentrated in vacuo to afford the subtitled compound as a pale yellow foam. Yield 0.254 g.
