実験手順

Tetrabutylammonium fluoride (1M in tetrahydrofuran, 2 mL) was added to a solution of (9-((4-(2-(tert-butyldimethylsilyloxy)ethyl)thiophen-2-yl)methyl)-1-oxa-4,9-diazaspiro[5.5]undecan-4-yl)(2-isopropylthiazol-4-yl)methanone (example 36, step a) (0.27 g) in tetrahydrofuran (4 mL). After 1 h, the solution was evaporated in vacuo. Purification by silica gel chromatography eluting with ethyl acetate:triethylamine, 20:1 gave the subtitled compound as a gum. Yield 0.18 g.
