実験手順

A solution of (2-isopropylthiazol-4-yl)(1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)methanone trifluoroacetate (example 22, step b) (0.294 g) in NMP (2 mL) was treated with acetic acid (0.039 mL) and stirred for 5 minutes. A solution of 2-chloro-5-(2-hydroxyethyl)benzaldehyde (example 61, step c) (0.189 g) in NMP (3 mL) was then added, the resulting solution was stirred for 1 hour and was then treated with sodium triacetoxyborohydride (0.217 g). The mixture was stirred overnight at room temperature, then poured into saturated sodium bicarbonate and extracted twice with ethyl acetate. The combined extracts were washed three times with water, once with brine, then dried over anhydrous magnesium sulphate and purified by flash chromatography on silica eluted with 1:2:97 triethylamine:methanol:dichloromethane to afford the subtitled compound as a colourless gum. Yield 0.238 g.
