実験手順

Trifluoroacetic acid (0.048 mL) was added to a solution of (9-(7-hydroxy-6,6-dimethylheptyl)-1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)(2-isopropylthiazol-4-yl)methanone (example 102, step c) (0.28 g) in DCM (15 mL) at 0° C. under argon and the mixture stirred for 5 min before addition of Dess-Martin periodinane (0.39 g). The reaction mixture was stirred at RT for 1 h then was quenched by addition of saturated sodium bisulfite solution (10 mL) and saturated sodium bicarbonate solution (10 mL) then ethyl acetate was added and the mixture stirred for 5 min. The layers were separated and the aqueous solution was extracted with ethyl acetate (×2). The combined organic solutions were washed with saturated sodium bicarbonate solution. Acetic acid (0.053 mL) was added to the organic phase which was then dried over sodium sulphate, filtered and evaporated in vacuo to afford the crude subtitled compound as a yellow oil. Yield 0.33 g.
