実験手順
TFA (0.08 mL) was added to a solution of (9-(3-fluoro-5-(2-hydroxyethyl)benzyl)-1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)(2-methylthiazol-4-yl)methanone (example 19, step b) (0.46 g) in DCM (5 mL) at 0° C. and the resulting mixture stirred for 5 min. Dess-Martin periodinane (0.68 g) was then added and the mixture stirred at RT for 45 min. Saturated sodium thiosulphate solution (5 mL), saturated sodium bicabonate solution (5 mL) and ethyl acetate (20 mL) were then added and the mixture stirred for 10 min. The aqueous phase was separated and extracted with ethyl acetate (20 mL). The combined organic solutions were washed with brine, acidified with acetic acid (0.1 mL), dried over sodium sulphate, filtered and evaporated in vacuo to give the subtitled compound as a yellow gum. Yield 0.4 g.
