실험 절차

Triton-B (40% in water, 0.94 mL) was added to a solution of (9-(2-chloro-3-(2-hydroxyethyl)benzyl)-1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)(2-ethylthiazol-4-yl)methanone [Example 26, step c] (3.2 g) and tert-butyl acrylate (1.5 mL) in acetonitrile (1 mL) and the resulting mixture stirred overnight at RT. The solvent was evaporated and the residue was purified by flash silica chromatography, elution gradient 1:1:0.05 ethyl acetate:isohexane:triethylamine to 95:5 ethyl acetate:triethylamine to give the subtitled compound as a clear oil. Yield 3.2 g.
