実験手順
A solution of 5-methylthiophene-2-sulfonyl chloride (0.15 g) in DCM (3 mL) was added dropwise to a solution of 2-(3-(1-oxa-4,9-diazaspiro[5.5]undecan-9-ylmethyl)-5-fluorophenyl)ethanol (example 55, step c) (0.21 g) and N-ethyl-N-isopropylpropan-2-amine (0.14 mL) in DCM (20 mL). The resulting mixture was stirred for 1 h and the solvent evaporated. The residue was partitioned between ethyl acetate (50 mL) and saturated sodium hydrogen carbonate solution (50 mL). The layers were separated and the aqueous extracted with ethyl acetate (2×50 mL). The combined organics were washed with brine (50 mL), dried over sodium sulphate, filtered and evaporated. The residue was purified by silica gel chromatography eluting with 47.5:47.5:5 ethyl acetate:isohexane:triethylamine to 95:5 ethyl acetate:triethylamine gradient. The fractions containing product were combined and evaporated to give the subtitled compound as a yellow gum. Yield 0.21 g.
